Cook the beef in a 10-inch skillet over medium-high heat until well browned, stirring often. Pour off any fat.
Stir the soup, salsa, milk, tortillas and half the cheese in the skillet. Spoon the beef mixture into a 2-quart shallow baking dish. Cover the baking dish.
Bake at 400 degrees F for 30 minutes or until the beef mixture is hot and bubbling. Sprinkle with the remaining cheese.
