Southwestern Casserole
Ingredients:

• 2 pounds ground beef
• 1 onion, chopped
• 2 8-ounce cans enchilada sauce
• 2 15-ounce cans chili beans in sauce
• 1 15-ounce package tortilla chips
• 1 8-ounce package shredded cheddar
• Sour cream for garnish

Directions:
Brown beef and onion together; drain. Stir in enchilada sauce and beans. Coarsely break up tortilla chips, reserving about 1/2 a cup. Arrange remaining chips in a lightly greased 13x9 baking dish. Spoon meat mixture on top. Sprinkle with reserved tortilla chips and cheese. Bake, covered, for 1 hour at 350 degrees. Remove from oven and serve immediately. 
Add some southwest seasoning to the meat mixture,  it is bland without it. I'd also have chopped tomato, olives and green onions for garnish.
