1. Prepare the Chicken: Pat the chicken breasts dry with paper towels. Slice each chicken breast horizontally to create two thinner cutlets, ensuring even cooking.

2. Season the Chicken: In a medium bowl, toss the chicken cutlets with olive oil, garlic powder, onion powder, smoked paprika, salt, and black pepper until each piece is evenly coated.

3. Cook the Chicken: Heat a large non-stick skillet over medium-high heat. Once hot, add the seasoned chicken. Cook for 4-6 minutes per side, or until the internal temperature reaches 165 F (74 C) and the chicken is golden brown and cooked through. Avoid overcrowding the pan; cook in batches if necessary.

4. Steam the Broccoli: While the chicken cooks, steam your broccoli florets. You can do this in a steamer basket over boiling water for 5-7 minutes until tender-crisp, or microwave them in a bowl with a splash of water, covered, for 3-4 minutes.

5. Assemble the Meals: Once the chicken is cooked, let it rest for a few minutes before slicing or dicing it into bite-sized pieces. Divide the cooked brown rice and steamed broccoli evenly among your meal prep containers.

6. Add Sauce and Optional Toppings: Drizzle each portion of chicken with about 1-2 tablespoons of low-sugar BBQ sauce. If desired, sprinkle with reduced-fat shredded cheddar cheese and garnish with fresh parsley.

7. Cool and Store: Allow the assembled meals to cool completely before sealing the containers and refrigerating. This prevents condensation and helps maintain freshness.
