Heat olive oil in a large 12-inch oven-safe skillet over medium-high heat.
Add chicken cubes, onion, and garlic to the skillet. Sauté until chicken is browned on all sides and onions are translucent, approximately 6 minutes.
Stir in the uncooked rice, chili powder, cumin, salt, and pepper. Cook for 1 minute to lightly toast the rice.
Pour in the chicken broth and enchilada sauce. Stir in the black beans and corn.
Bring the mixture to a boil, then reduce heat to low. Cover with a tight-fitting lid and simmer for 18 to 20 minutes, or until the rice is tender and the liquid is absorbed.
Preheat the oven broiler to high.
Remove the lid and sprinkle the shredded cheese and tortilla strips evenly over the chicken and rice mixture.
Place the skillet under the broiler for 2 to 3 minutes until the cheese is melted and bubbling and the tortilla strips are lightly toasted.
Remove from the oven and allow to rest for 5 minutes before serving.
