1. Prepare the Poultry: Preheat oven to 400°F (200°C). Pat chicken dry with paper towels. In a bowl, toss chicken with 1 tbsp olive oil, paprika, garlic powder, onion powder, salt, and pepper until evenly coated. Place chicken on a baking sheet.
2. Roast Chicken: Bake for 20-25 minutes, or until internal temperature reaches 165°F (74°C). Let rest for 5 minutes before slicing or shredding.
3. Cook Quinoa: While chicken roasts, combine rinsed quinoa and broth in a medium saucepan. Bring to a boil, then reduce heat to low, cover, and simmer for 15 minutes, or until all liquid is absorbed. Fluff with a fork.
4. Prepare Roasted Vegetables: On a separate baking sheet, toss broccoli, bell peppers, and red onion with 1 tbsp olive oil, salt, and pepper. Roast in the same oven as the chicken for 15-20 minutes, or until tender-crisp and slightly caramelized.
5. Assemble Meal Prep Containers: Divide the cooked quinoa, sliced/shredded chicken, and roasted vegetables evenly among 4-5 meal prep containers.
6. Store and Reheat: Allow meals to cool completely before sealing containers and refrigerating. They can be stored for up to 4-5 days. Reheat in the microwave until warmed through.
