01 - Combine cooked chicken, diced bell peppers, chopped onion, ground cumin, chili powder, garlic powder, salt, and black pepper in a medium bowl. Mix thoroughly to distribute spices evenly.
02 - Place a large skillet over medium heat. Add a small amount of olive oil or butter to lightly coat the surface.
03 - Lay one tortilla flat in the preheated skillet. Distribute 1/2 cup shredded cheese evenly over half of the tortilla surface.
04 - Spoon 1/2 cup of the seasoned chicken mixture over the cheese layer. Top with chopped cilantro and jalapeño if desired.
05 - Fold the tortilla over to create a half-moon shape, enclosing the filling. Cook for 2-3 minutes until the bottom becomes golden brown and crispy.
06 - Carefully flip the quesadilla and cook the second side for 2-3 minutes until golden brown and the cheese has completely melted.
07 - Transfer the cooked quesadilla to a cutting board. Allow to rest for 1 minute before cutting into 3-4 wedges.
08 - Continue the process with remaining tortillas and filling. Serve immediately with salsa, sour cream, guacamole, and fresh lime wedges.
