When enchiladas are served in Mexico, they are often a bit heavy and meaty, but these chicken-filled tortillas are light and delicious. You can make this your own by choosing your favorite salsa. Some like it mild, while others like it hot. You can substitute chicken with beans and rice if you want to go vegetarian. No matter what you your preference, this dish is great made ahead and then placed in the oven when you are ready to eat.
