Season the chicken breasts with chili powder, cumin, garlic powder, onion powder, salt, and pepper.
Heat olive oil in an oven-safe skillet over medium-high heat. Sear the chicken breasts for 2-3 minutes per side until browned.
Transfer the skillet to the preheated oven and bake for 15-20 minutes, or until the chicken is cooked through and reaches an internal temperature of 165ยฐF (74ยฐC).
Remove the chicken from the skillet and let it rest for 5 minutes. Shred or dice the chicken.
Assemble the bowls: Divide the cooked rice among serving bowls. Top with shredded chicken, black beans, and corn.
Pour enchilada sauce over the ingredients in each bowl.
Sprinkle shredded cheddar cheese on top.
Bake for 5-10 minutes, or until the cheese is melted and bubbly.
Add your favorite optional toppings before serving.
Notes
You can use rotisserie chicken for a quicker option.
Adjust the spice level by adding more or less chili powder.
For a vegetarian option, substitute the chicken with seasoned tofu or extra beans.
