Creating this amazing dish can be simple if you follow these step-by-step instructions:

1. Preheat Oven: Preheat your oven to 375°F (190°C).
2. Prepare Chicken: In a bowl, combine olive oil, smoked paprika, cumin, chili powder, garlic powder, onion powder, salt, and black pepper to create a marinade.
3. Marinate Chicken: Coat the chicken breasts well in the marinade, ensuring they are fully covered. Allow the chicken to marinate for at least 30 minutes, or overnight for more intense flavor.
4. Prepare Vegetables: While the chicken marinates, slice the red and yellow bell peppers and red onion.
5. Combine Ingredients: On a baking sheet, lay the marinated chicken breasts in the center. Scatter the sliced bell peppers, red onion, and corn around the chicken.
6. Bake: Place the baking sheet in the preheated oven. Bake for 25-30 minutes, or until the chicken reaches an internal temperature of 165°F (75°C) and the vegetables are tender.
7. Garnish and Serve: Remove from the oven and let cool for a few minutes. Sprinkle fresh cilantro over the top for a pop of color and flavor.
