A favorite of ours when we first got married. I need to make this again since it is so easy and good.
1 pound ground beef
1 onion, chopped
1/2 cup sour cream
8 oz salsa
1 can cream of mushroom soup
6 corn tortillas ( I use flour and it is much better IMHO)
2 cups shredded cheddar
Cook Ground Beef and Onion in pot. Drain. Blend Salsa, sour cream and soup in seperate bowl. In greased casserole dish or glass pan put some of the salsa in bottom of pan. Layer tortillas, beef, sauce and repeat. Top with cheese.
Bake 350 degrees uncovered for 30 minutes till hot and bubbly. Let stand 10 minutes before serving.
