In a large skillet, over medium high heat, brown beef. Add green chilies, taco seasoning and water. Let reduce, about 3 minutes.
Spray a large casserole dish (9x13") with cooking spray.
Pour about 1/4 cup enchilada sauce in bottom of baking dish. Lay 6 tortillas over the sauce. Spread a 1/3 of the refried beans over tortillas and 1/3 of the beef mixture over beans. Top with a handful of cheese. Repeat the process (1/4 cup enchilada sauce, tortillas, beans, beef, cheese). End with cheese on the top layer.
Bake covered with foil for 20 minutes. Remove foil and bake another 10 minutes or until cheese on top is melted.
Serve with sour cream, salsa, avocado...
Notes:
* Do not use too much enchilada sauce. If the dish looks too "soupy" back off on the amount of sauce used.
* If you don't have corn tortillas then use flour
* Use ground turkey, ground chicken, pulled chicken in place of beef if you prefer
