2 cups crushed corn chips, divided
1-1/2 lb. ground beef
1 can (15 oz.) tomato sauce
1 envelope taco seasoning
1 cup (8 oz.) sour cream

In a large skillet, cook beef over medium heat until no longer pink; drain. Stir in tomato sauce and taco seasoning; bring to a boil. Reduce heat; simmer, uncovered, for 5 minutes. Spoon over chips. Top with sour cream, cheese and remaining chips. Bake, uncovered, at 350 for 25-30 minutes or until crust is lightly browned.
