Step-by-Step Cooking Instructions

1. Preheat and Prepare

Preheat your oven to 400°F (200°C) and grease a baking dish.

In a small bowl, mix all the spices (chili powder, paprika, cumin, garlic powder, onion powder, salt, and black pepper).
Coat the chicken breasts with 1 tbsp of olive oil and sprinkle the spice mix evenly on both sides.

3. Arrange the Vegetables

In a large bowl, toss the sliced bell peppers and onion with 1 tbsp olive oil, a pinch of salt, and lime juice.
Spread the vegetables in a single layer in the baking dish.
Place the seasoned chicken on top of the vegetables.

4. Bake to Perfection

Bake uncovered for 22-25 minutes, or until the internal temperature of the chicken reaches 165°F (75°C).
For a charred fajita effect, broil for an additional 2-3 minutes.
