Step 1: Start by slicing the chicken breasts into thin strips. Dice the onion and bell peppers into bite-sized pieces.
Step 2: In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add the diced onions and bell peppers, and sauté for about 5 minutes until softened.
Step 3: Add the sliced chicken to the skillet. Sprinkle in the paprika and fajita spice mix. Cook until the chicken is no longer pink, about 6-7 minutes.
Step 4: Lay out the tortillas. On one half of each tortilla, place a generous amount of the chicken and vegetable mixture, then sprinkle cheese on top.
Step 5: Fold the tortillas in half and cook each folded quesadilla in the skillet for about 3-4 minutes on each side until golden brown and cheese is melted.
Step 6: Remove from skillet, let rest for a minute, then cut into wedges. Serve warm with dips like salsa or guacamole.
Notes
For extra flavor, marinate the chicken in fajita spice mix for 30 minutes before cooking. Feel free to add other vegetables or adjust spice levels.
