Richard's Favorite Enchilada casserole

I love enchiladas, but when it comes to weeknight dinners I tend to go for effect over detail. Why roll up individual enchiladas when you can layer it all in half the time? I always make this with chicken, but it occurs to me that this could be a perfect way to use up left-over turkey. Throw some Spanish rice and refried beans on the side and you'll feel like you went out to one of those weird Mexican restaurants that all have different names but identical, numbered menus. (Is that just a Memphis thing?)

1 pkg (at least 24) corn tortillas (Do NOT use flour. I mean it. CORN!)
1 large can or 2 regular-sized cans red enchilada sauce
1 small can tomato sauce
1 can cream of chicken soup
1 16 oz (or larger) carton sour cream
About 4 cups cooked chicken or turkey, shredded or chopped (I guess--I don't really measure anything. I use one whole chicken or four breasts usually.)
1 can whole green chiles
8 ounces shredded cheddar or Mexican blend or casserole blend cheese

Mix enchilada sauce and tomato sauce in a small bowl or large measuring cup and pour a small amount in the bottom of a rectangular baking dish (just enough to cover the bottom with a thin layer).

In another bowl, mix chicken, cream of chicken soup, and half the sour cream.

Cover the sauced bottom of dish with a layer of tortillas. It's fine if they overlap substantially, but don't leave any gaps. I use 8 per layer in my 9X13 dish. Cover tortillas with half the chicken mixture, spreading to make a somewhat even layer. Tear half the chiles into strips and arrange over chicken. Sprinkle with 1/3 of cheese, then drizzle with a thin layer of sauce. Repeat layers, starting with tortillas, using all the remaining chicken mixture and chiles, 1/3 of cheese, and another thin layer of sauce. Top with last layer of tortillas, then pour all remaining sauce evenly over casserole. Cover with foil and bake at 375 for 45 minutes. Remove foil, add remaining cheese, and bake another 10-15 minutes until most of sauce has been absorbed and the whole thing is bubbly. Let stand 5-10 minutes before cutting or it will not retain it's shape when served. Serve with remaining sour cream as garnish.
