Pre heat oven to 350 degrees F.
In a medium pan, heat oil and add onions and green peppers. Sautee for 2-3 minutes, then add chicken and 3/4 of the enchilada sauce. Heat for another 8-10 minutes or until chicken is completely cooked. Season with salt and pepper to taste.
Fill each tortilla with a good amount of chicken mixture, and add in some green chilis, beans, and corn. Close the tortilla and place in a large baking dish.
