Mexican Casserole

We love this at our house any time of year.

1 lb ground beef

1 cup chopped olives

1/2 tsp. garlic salt

1 Tbsp chopped onion

2 (8oz) tomato sauce

1 cup cottage cheese

1 cup sour cream

1 can diced green chilies

8 oz. tortilla chips

2 cups grated cheese

Brown Hamburger. Drain and add garlic salt, tomato sauce, olives and onion. In a separate bowl, combine sour cream, cottage cheese, and green chilies. Spray casserole dish with cooking spray. Layer 1/2 of chips (crush them a little to lay flat), then meat mixture, next sour cream mixture and cheese. Repeat layers, ending with cheese. Bake, covered, at 350 for 35 minutes.
