TL;DR: If you want to add more protein to your week, you do not have to rely on chicken, eggs, or protein powder alone. These surprising foods with protein can help round out your meals, snacks, and smoothies, and they fit especially well into a realistic meal prep routine.
When I'm helping someone build a more balanced meal prep routine, one of the first things I look at is protein variety. It is easy to fall into the same pattern of chicken, fish, eggs, and beans every week. Those staples work, but they are not the only way to support your goals.

That is where these surprising foods with protein come in. Some of them are snack-friendly, some work well in breakfast or lunch meal prep, and a few are great supporting players that make meals more satisfying. A couple are more moderate protein sources than true high-protein foods, but they can still help you build a more balanced plate when paired with other ingredients. If you are trying to eat better without overthinking every meal, this kind of flexibility matters.
I also like this list because it works in real life. You can add these foods into bowls, smoothies, breakfast prep, or quick snacks without making your week harder. That is usually the sweet spot for consistency. For more ideas like this, browse these High Protein Recipes or explore the full Recipe Index.

How To Build Meals With These Foods
This roundup works best when you think of it as a meal prep toolkit. Some of these ingredients are true protein contributors, and others help round out a meal with texture, fiber, healthy fats, or staying power.
Step 1: Start With The Stronger Protein Picks
If your goal is to make meals more filling, begin with the foods on this list that give you the biggest protein boost per practical serving:
- Green peas: about 8 grams of protein per cup
- Oatmeal: about 6 grams per cup cooked, depending on brand and preparation
- Pistachios: about 6 grams per ounce
- Goat cheese: about 6 grams per ounce
- Spinach: a smaller but still helpful amount, especially in cooked portions
- Walnuts and avocado: better thought of as supportive ingredients, since they add some protein but shine more for fats, fiber, and overall balance
That distinction matters. Not every food has to carry the whole protein load by itself. I've found it is usually easier to combine a few moderate sources than to force every meal into the same formula.

Step 2: Pair Them With Foods You Already Enjoy
This is where meal prep gets easier. You do not need a completely new system. You just need a few smart pairings.
Try combinations like:
- Oatmeal topped with pistachios and walnuts
- Spinach and goat cheese folded into egg muffins
- Green peas added to grain bowls or pasta salad
- Avocado layered into wraps with turkey or tofu
- Pistachios sprinkled over yogurt or cottage cheese
- Goat cheese added to a roasted veggie lunch box
These are the kinds of upgrades that help a meal feel more complete without adding much extra work.
Step 3: Use Smoothies To Fill In The Gaps
Smoothies can be a great backup plan when your week gets busy. I do not think every smoothie needs to become a giant protein bomb, but it is helpful to know how to make one more balanced.
A better smoothie usually includes:
- A fruit or vegetable base
- A protein source
- A healthy fat
- Enough liquid for texture
- Optional fiber boosters like seeds or greens
That structure gives you something that feels satisfying instead of a drink that leaves you hungry an hour later.

7 Surprising Foods With Protein
1. Pistachios
Pistachios are one of my favorite snack-prep ingredients because they are easy to portion and easy to use in more than one way. One ounce offers around 6 grams of plant-based protein, plus fiber and healthy fats.
They work well as:
- A quick snack
- A crunchy topping for oatmeal
- A salad topper
- A mix-in for homemade trail mix
For meal prep, portion them into small containers or snack bags so they are ready to grab.
2. Avocado
Avocado is often talked about for healthy fats, and that is really where it stands out. It does contain a little protein, but I would not call it a high-protein food on its own. Still, it absolutely earns a place in a balanced meal prep plan because it adds creaminess, satisfaction, and staying power.
I like avocado in:
- Breakfast toast with eggs
- Turkey wraps
- Grain bowls
- Smoothies for a creamy texture
Think of avocado as a supporting ingredient that helps a protein-focused meal feel more satisfying.

3. Walnuts
Walnuts bring about 4 grams of protein per ounce, along with heart-healthy fats. Like avocado, they are not the star protein source in a meal, but they are a smart add-on.
Use walnuts in:
- Overnight oats
- Salads
- Snack boxes
- Homemade granola
- Smoothies
A little goes a long way, which makes them useful for both flavor and texture.
4. Spinach
Spinach is one of those ingredients that quietly makes everything better. It offers a modest amount of protein, especially when cooked, and it is also packed with nutrients.
I use spinach in meal prep because it is versatile:
- Toss it into smoothies
- Add it to pasta dishes
- Sauté it for breakfast bowls
- Layer it into wraps and sandwiches
- Stir it into soups
If you have ever bought spinach with good intentions and then forgotten it in the fridge, you are not alone. Prepping it right away makes all the difference.

5. Goat Cheese
Goat cheese adds tang, creaminess, and around 6 grams of protein per ounce. It is one of the easiest ways to add flavor to meal prep without needing a heavy sauce.
Try it in:
- Egg bites
- Roasted veggie bowls
- Toasts and flatbreads
- Salads
- Stuffed chicken breasts
Because the flavor is strong, a small amount goes a long way.
6. Oatmeal
Oatmeal deserves more credit in the protein conversation. It is still mostly known for fiber, but it also contributes protein and works as a great base for a filling breakfast.
I like oatmeal because it is:
- Budget friendly
- Easy to batch cook
- Adaptable for sweet or savory meals
- A solid option for busy mornings
To boost the protein even more, pair it with Greek yogurt, chia seeds, nuts, or a scoop of protein powder.
7. Green Peas
Green peas might be the most underrated food on this list. They are affordable, freezer-friendly, and surprisingly helpful when you want to add more protein to lunches or dinners.
Use peas in:
- Fried rice
- Pasta salads
- Chicken bowls
- Shepherd's pie
- Blended dips
- Quick soups
Frozen peas are especially practical for meal prep because they are ready when you need them and do not spoil as quickly as fresh produce.
3 Protein Smoothies To Try
Almond Avocado Matcha Smoothie
This one is creamy, lightly earthy, and easy to customize.
What you need:
- ½ avocado
- 1 teaspoon matcha
- 1 tablespoon almond butter
- 1 cup vanilla almond milk
- 1 cup ice
- Optional: 1 chopped pear
- Optional: red lettuce for extra greens
Meal prep tip: Freeze the avocado and pear in smoothie packs so you can blend this fast on busy mornings.
Green Protein Smoothie
This is a good option when you want something fresh and produce-forward.
What you need:
- 1 ounce kale
- ½ avocado
- 4 ounces pineapple juice
- 1 peeled tangerine
- Water
- Ice
- Optional: almonds
- Optional: pea protein
Best way to reheat? No reheating here, but this is a good example of a smoothie that benefits from extra protein added in, especially if you want it to hold you over longer.

Orange Pineapple Smoothie
This one is bright, tasty, and easy to keep simple.
What you need:
- 1 peeled orange
- 4 ounces pineapple juice
- 1 tablespoon hemp seeds
- 1 tablespoon goji berries
- Water
- Ice
This is more of a refreshing support smoothie than a full meal replacement unless you add something with more protein, such as Greek yogurt or protein powder.
How To Store
If you are wondering how to store this meal prep, the answer depends on which ingredient or smoothie you are making.
For Nuts, Oats, And Seeds
- Store in airtight containers
- Keep in a cool, dry pantry
- For longer freshness, refrigerate nuts after opening
For Spinach, Avocado, And Goat Cheese
- Store spinach dry with a paper towel in the container to reduce moisture
- Keep avocado whole until ready to use when possible
- If storing cut avocado, press plastic wrap tightly against the surface and add lemon or lime juice
- Keep goat cheese sealed and refrigerated
For Peas
- Frozen peas are easiest for meal prep
- Keep them in the freezer until needed
- Cooked peas can be stored in the fridge for 3 to 4 days
For Smoothies
- Store blended smoothies in sealed jars in the fridge for up to 24 hours for best texture
- Smoothie freezer packs can be stored for up to 2 months
- If you are asking can I freeze this, yes, most smoothie ingredients freeze very well before blending

How To Reheat
The best way to reheat these foods depends on how you used them in your prep.
Oatmeal
- Microwave with a splash of milk or water for 60 to 90 seconds
- Stir halfway through for a creamier texture
Peas
- Microwave for 30 to 60 seconds
- Or warm quickly in a skillet with a little olive oil
Spinach
- Reheat gently in a skillet just until warmed through
- Avoid overcooking so it does not turn overly soft
Goat Cheese
- Usually best added after reheating hot dishes
- If baked into egg bites or casseroles, reheat the full dish as usual
Smoothies
- Do not reheat
- If frozen after blending, thaw overnight in the fridge and shake well before drinking
Nutrition Facts
Because this is a roundup rather than one single recipe, nutrition will vary by serving size and brand. Here is a quick reference using the amounts mentioned in the source material:
- Pistachios, 1 ounce: about 6g protein
- Goat cheese, 1 ounce: about 6g protein
- Oatmeal, 1 cup prepared: about 6g protein
- Green peas, 1 cup: about 8g protein
- Walnuts, 1 ounce: about 4g protein
- Spinach, cooked serving: moderate protein contribution
- Avocado: small protein contribution, plus healthy fats and fiber
For the best results, pair these with your main protein sources and use a tool like the MPOF Macro Calculator if you want to tailor meals more closely to your goals.
Helpful Tips Or Ingredient Swaps
- Add Greek yogurt, cottage cheese, or protein powder to smoothies if you want them to be more filling
- Use frozen spinach or peas when fresh produce is not practical
- Swap goat cheese for feta if that is what you already have
- Mix oats with chia seeds or hemp seeds for extra texture and nutrition
- Pair avocado with a stronger protein source instead of relying on it alone
- Build snacks around protein plus fiber, like pistachios with fruit or oats with nuts
Final Thoughts
Protein does not have to come from the same three foods every single week. That is probably my favorite takeaway from this roundup. When you have a handful of flexible ingredients that fit into breakfast, lunch, snacks, and smoothies, healthy eating feels much more doable.
I've found that meal prep gets easier when you stop chasing perfection and start building a system that works with your real schedule. These foods help with that. They are practical, flexible, and easy to work into meals you already like.
