Heat the olive oil in a large skillet over medium heat. Add the chicken pieces, cumin, chili powder, and salt. Cook for 5 to 6 minutes, stirring occasionally, until the chicken is no longer pink on the outside.
Add the diced onion and minced garlic to the skillet. Cook for 2 minutes until the onion begins to soften.
Pour in the enchilada sauce, then add the black beans and frozen corn. Stir to combine and bring the mixture to a gentle simmer.
Stir in the corn tortilla strips until they are coated in sauce. Let everything simmer for 3 minutes so the tortillas soften.
Sprinkle the shredded cheese evenly over the top. Cover the skillet and cook for 2 to 3 minutes until the cheese melts.
