Tortilla Tower (what we've always called it)- could also be called Enchilada Casserole.
Here's what you need:
Corn Tortillas- probably a dozen or more, we like a lot of tortillas in it.
1 can refried beans
1 lb. ground beef cooked
1 can enchilada sauce (I use the small can but if you like enchiladas really wet, you can get the large can)
1 can sliced black olives
First pour a small amount of enchilada sauce in the bottom of a 9x13 baking pan, just enough to give a light coating. Then lay down a layer of corn tortillas; I usually break them down to make sure the corners have tortilla in them.
