01 - In a medium bowl, combine the shredded chicken with cumin, smoked paprika, garlic powder, salt, and black pepper. Toss until the chicken is evenly coated with the spice mixture.
02 - Heat 1 tablespoon of oil in a large skillet over medium heat. Add the onion, bell pepper, and jalapeño. Sauté for 3–4 minutes until softened. Add the seasoned chicken and stir to combine. Cook for 2 additional minutes, then transfer the mixture to a bowl and wipe out the skillet.
03 - Lay out the tortillas on a clean surface. On one half of each tortilla, sprinkle a quarter of the cheese, top with a quarter of the chicken mixture, then add another layer of cheese. Fold each tortilla in half to form a half-moon shape.
04 - Heat the remaining oil in the skillet over medium heat. Place 1–2 quesadillas in the pan (do not overcrowd). Cook for 2–3 minutes per side, pressing gently with a spatula, until the tortillas are golden and crispy and the cheese is completely melted.
05 - Transfer the quesadillas to a cutting board and let rest for 1 minute. Cut each quesadilla into wedges and serve hot with sour cream, salsa, cilantro, and lime wedges as desired.
