01 - In a medium bowl, combine shredded chicken with cumin, smoked paprika, garlic powder, salt, and black pepper. Toss until evenly coated.
02 - Heat 1 tablespoon oil in a large skillet over medium heat. Add onion, bell pepper, and jalapeño. Sauté for 3-4 minutes until softened, then add seasoned chicken. Stir to combine and cook for 2 additional minutes. Transfer mixture to a bowl and wipe out skillet.
03 - Lay out tortillas on a clean surface. On half of each tortilla, layer one-quarter of the cheese, followed by one-quarter of the chicken mixture, then another layer of cheese. Fold tortillas in half to form half-moon shapes.
04 - Heat remaining oil in the skillet over medium heat. Place 1-2 quesadillas in the pan. Cook for 2-3 minutes per side, pressing gently with a spatula, until tortillas are golden and crispy and cheese is melted. Repeat with remaining quesadillas.
05 - Transfer quesadillas to a cutting board. Let rest for 1 minute, then cut into wedges. Serve hot with sour cream, salsa, cilantro, and lime wedges as desired.
