How to Make

This chicken fajita veggie meal prep comes together quickly, which is one reason I like it so much for busy weeks. Once the veggies are sliced and the cauliflower rice is ready to go, the rest moves fast.

Step 1: Sauté The Peppers And Onions

Heat a large skillet over high heat and add oil. Once the pan is hot, add the sliced onions and peppers.

Cook for about 5 to 7 minutes, stirring occasionally, until the vegetables are slightly tender but still have a little bite. That bit of texture helps them hold up better for meal prep.

Step 2: Cook The Cauliflower Rice

In a separate skillet, heat the remaining oil over medium-high heat. Add the cauliflower rice and cook for about 10 minutes, stirring every couple of minutes so it cooks evenly and doesn't stick.

This step is important because you want to cook off excess moisture. That's the best way to keep your meal prep from getting watery in the fridge.

Step 3: Add The Chicken And Seasoning

Once the cauliflower rice is cooked, add the fajita seasoning and chicken to the pan. Sauté until the chicken is warmed through and any extra liquid has reduced.

If your chicken is already fully cooked, this step goes quickly. You're mainly looking to coat everything evenly with seasoning and bring the flavors together.

Step 4: Assemble Your Meal Prep Containers

Divide the cauliflower rice and fajita veggies between meal prep containers. Spoon on salsa verde, then top with Greek yogurt, scallions, avocado if using, and a squeeze of fresh lime.

Finish with chopped cilantro for a bright, fresh flavor that ties everything together.

How to Portion This Meal Prep

Because there are sides incorporated into this dish, we recommend using three-compartment meal prep containers to store it.

You can place the chicken, peppers, and onions in one compartment, cauliflower rice in another, and reserve toppings like salsa verde, yogurt, and avocado for the third. This setup also makes reheating much easier.

Helpful Tips And Ingredient Swaps

• Use pre-cooked chicken strips if you want to cut prep time even more. This makes the recipe especially convenient for weekday batch cooking.
• Swap the Greek yogurt for your favorite dairy-free or vegan alternative if needed. This works well for anyone who is lactose intolerant.
• Don't overcook the peppers and onions. Keeping a little texture helps them hold up better in the fridge.
• Cook off excess moisture in the cauliflower rice so your containers stay fresher and don't get soggy.
• Add avocado right before serving if possible. It keeps the color and texture much better that way.
