Ingredients
1 bag frozen onion
3lb ground beef
2 cans refried beans
2 cans cream of mushroom soup
4 oz sour cream
Tortillas
Shredded cheese (I used Colby jack)
3 packets taco seasoning
Directions:
Brown the beef, drain, and add the frozen onion. Add taco seasoning. Add refried beans. Meanwhile, mix cream of mushroom and sour cream together. Layer half of the sour cream/cream of mushroom mix in the bottom of the casserole dish. Add torn up (or cut up) tortillas. Add half the meat/bean mixture. Add layer of cheese. Repeat the layers again. Finish with a good layer of cheese. Bake a 350 for 30 minutes.
I just layer the tortillas whole now. Also, for some texture maybe add some tortilla chips to the top in the last 5 minutes.
