Enchilada Casserole

No one makes this better than my mother!  She takes it to pot lucks and everyone raves about it.

• 2 lbs ground beef
• 1 cup chopped onion
• garlic salt
• 1 can cream of mushroom soup
• 2 small cans green chilies
• corn tortillas (I use around 5)
• shredded cheese

Brown meat in large stock pot with onions and garlic salt.  Drain any fat off meat.  Add soup with a half can of water and chilies.  Bring to a simmer over low heat.  Tear your tortillas up and place on top, pushing them down into the juices.  Sprinkle with cheese, cover and let simmer until cheese is melted.  Garnish with sour cream, salsa, lettuce, & tomatoes.
