Heat olive oil in a skillet over medium heat.
Sauté onions and bell peppers until softened.
Add cooked chicken and corn to the skillet, mixing well.
Season with salt, pepper, and cilantro.
In the same skillet, place one tortilla and sprinkle half with cheese.
Add a portion of the chicken mixture on top of the cheese.
Sprinkle more cheese over the filling, then fold the tortilla in half.
Cook for 2-3 minutes on each side until golden brown and cheese is melted.
Repeat with remaining tortillas and filling.
