Use either a 9x13 baking pan or 2 (8-inch) pie plates.
Spoon a small amount of enchilada sauce in the bottom of the pan.
Then, you can either fill the tortillas with the beans, shredded chicken, cheese and enchilada sauce--or you can layer ingredients in this order: tortillas (tear to fit the pan), refried beans (spread over tortilla), shredded chicken, enchilada sauce, cheese.
Repeat layers until pan is full.
Add a final layer of tortillas, enchilada sauce, and cheese.
