Shape meat into 4 (1/2-inch-thick) patties. Grill 7 to 9 min. on each side or until done (160ºF). Top with VELVEETA; grill 1 min. or until melted.
Fill buns with cheeseburgers and mayonnaise mixture.
Notes
How to Turn Hamburgers:
When cooking ground beef patties, turn them over with a spatula. Do not flatten the patties during the cooking process since that will cause the juices to escape, resulting in dry cooked burgers.
