Follow these easy steps to create your delicious Fiesta Chicken:

1. Prepare the Chicken: Start by patting chicken breasts dry. This will help them sear better.
2. Season the Chicken: In a bowl, mix olive oil, chili powder, cumin, paprika, garlic powder, onion powder, salt, and pepper. Coat the chicken with this spice mixture.
3. Heat a Pan: In a large skillet over medium-high heat, add a little olive oil and let it heat up.
4. Cook the Chicken: Place the seasoned chicken breasts in the skillet. Sear for 5-7 minutes on each side until golden brown and cooked through.
5. Remove Chicken: Once cooked, take the chicken out of the pan and let it rest on a cutting board.
6. Add Vegetables: In the same skillet, add corn, black beans, red and green bell peppers, and diced tomatoes. Cook for 5-7 minutes until veggies are slightly softened.
7. Slice Chicken: While the veggies are cooking, slice the chicken into strips.
8. Combine Ingredients: Add the sliced chicken back to the skillet and stir everything together. Cook for another 2-3 minutes to heat through.
9. Garnish: Once fully warmed, sprinkle fresh cilantro over the top for added flavor.
10. Plate the Dish: Serve the Fiesta Chicken hot, garnishing with avocado slices and lime wedges.
