2. in a large skillet over medium-high heat, cook ground beef until no longer pink. stir in salsa, reduce heat, and simmer 20 minutes, or until liquid is absorbed. stir beans, and heat through.
3. spray 9x13 baking dish with cooking spray. spread crushed chips in dish, and then spoon beef mixture over chips. spread sour cream over beef, and sprinkle olives, green onions, and tomato over the sour cream. top with cheese.
