How to Make Garlic and Thyme Chicken Meal Prep
- Preheat oven: Set oven to 425°F and line a sheet pan with parchment paper or foil.
- Season chicken: Place chicken in a bag or bowl. Add 1 tablespoon olive oil, garlic, thyme, ¼ teaspoon pepper, and ½ teaspoon salt. Rub until evenly coated.
- Prep vegetables: Toss brussels sprouts with 1 tablespoon olive oil. Microwave chopped sweet potato for 3 minutes to soften, then toss with a drizzle of oil. Season both with remaining salt and pepper.

- Serve: Garnish with fresh thyme and portion into containers.

How to Store
- Fridge: Store in airtight containers for up to 4 days.
