Sauté aromatics: Heat olive oil in a large skillet over medium heat. Add diced onion and sauté until soft and translucent, about 3-4 minutes.
Add chicken & season: Stir in shredded chicken, cumin, paprika, salt, and pepper. Cook for 2 minutes to warm through and coat in spices.
Mix in sauce & tortillas: Pour in the enchilada sauce and mix well. Add tortilla strips, black beans, and corn. Stir everything together and simmer for 5 minutes.
Top with cheese: Sprinkle shredded cheese over the top. Cover the skillet and cook for another 3–4 minutes until cheese is melted and bubbly.
Serve: Remove from heat and garnish with sour cream, avocado slices, chopped cilantro, or a squeeze of lime. Serve hot and enjoy!
