Creating BBQ Chicken with Sweet Potatoes and Bell Peppers is straightforward. Follow these simple steps to achieve a flavorful meal:

1. Preheat the Oven: Preheat your oven to 400°F (200°C).
2. Prepare the Marinade: In a small bowl, mix together the BBQ sauce, olive oil, garlic powder, onion powder, paprika, salt, and black pepper.
3. Prep the Chicken: Place the chicken breasts in a shallow dish and pour half of the marinade over them. Make sure to coat each piece evenly.
4. Marinate: Let the chicken sit for at least 30 minutes. If you have time, marinating it overnight will deepen the flavors.
5. Prepare the Vegetables: In a separate bowl, toss the cubed sweet potatoes and chopped bell peppers with the remaining marinade until evenly coated.
6. Arrange in Baking Dish: Transfer the marinated chicken to a baking dish and surround it with the sweet potatoes and bell peppers.
7. Bake: Place the baking dish in the preheated oven and bake for 30-40 minutes, or until the chicken is cooked through and the sweet potatoes are tender.
8. Check for Doneness: Use a meat thermometer to ensure the chicken reaches an internal temperature of 165°F (75°C).
9. Garnish and Serve: Once done, remove from the oven, let it rest for a few minutes, and garnish with fresh parsley if desired.
