Mary's Trainwreck Casserole

*Cook a roast in a crockpot with green enchilada sauce, a can of diced peppers, diced onions, 2 cans rotel, lots of taco seasoning, diced jalapenos, and a little bit of minced garlic. I usually cook on low for 7 hours-ish. Take the roast out of the crockpot and shred it.
*Add a little flour or corn starch to the sauce that is left in the crockpot and stir til it looks a little thicker.
*To construct the casserole, put some of the sauce in a dish (I like to use a 9x13), then put down tortillas on top of the sauce to cover the entire surface. Put 1/3 of the shredded beef over the tortillas and top with more sauce. Add a layer of grated cheese (I use a mixture of cheddar and monterey jack). Keep repeating this sequence until you are to the top of your dish. top with cheese.
*Bake at 350 for 20-30 minutes.
(This recipe doesn't freeze well--only due to the tortillas in the casserole. You could freeze the shredded beef in the sauce to hurry the process)
