Preheat the oven to 400°F.
Shred the chicken and combine it with the queso fresco and cheddar cheese.
Lay the tortillas on a cutting board or plate. On the bottom half of each of the tortillas, sprinkle 2 tablespoons of the cheese mixture. Then, layer the chicken, red pepper, onion, and cilantro on top of each of the tortillas. Each tortilla should have an equal amount of each ingredient.
Sprinkle an additional 2 tablespoons of the cheese mixture on top of each of the tortillas.
Fold the top half of each of the tortillas over the bottom half to cover the filling. Move to a cookie sheet lined with foil.
Lightly spray the tops of each of the tortillas with the olive oil. Place the cookie sheet in the oven. Bake for 8 to 10 minutes or until golden brown and heated through.
