Prep the ingredients: Dice the chicken, onion, and bell pepper. Cut tortillas into thin strips.
Rinse and drain the black beans. Keep everything within reach.
Sear the chicken: Heat olive oil in a large skillet over medium-high. Season chicken with a pinch of salt and pepper.
Cook 4–6 minutes, stirring occasionally, until lightly browned and just cooked through. Transfer to a plate.
Sauté aromatics: In the same skillet, add onion and bell pepper with a small pinch of salt. Cook 3–4 minutes until softened.
Stir in garlic, cumin, chili powder, and smoked paprika. Cook 30 seconds, just until fragrant.
Add sauce and mix-ins: Lower heat to medium. Stir in enchilada sauce, black beans, corn, and the cooked chicken.
Simmer 2–3 minutes to let flavors come together.
Fold in tortillas: Add tortilla strips and gently fold to coat. They should soften and thicken the skillet. If it looks too thick, add a splash of water or broth; too thin, add a few more tortilla strips.
Melt the cheese: Sprinkle shredded cheese evenly over the top.
Cover the skillet and cook 2–3 minutes, just until the cheese melts.
Add Greek yogurt: Turn off the heat. Dollop Greek yogurt over the skillet and gently swirl it in for creaminess. Taste and adjust salt and pepper.
Finish and serve: Top with chopped cilantro and a squeeze of lime.
Add optional toppings if you like. Serve hot right from the skillet.
