The chopped cheese sandwich originated in Harlem, New York City, and is a beloved staple of local bodegas. It consists of ground beef (chopped while cooking), onions, melted cheese, lettuce, tomato, and condiments, all served on a hero roll. It's often compared to a cheeseburger or a Philly cheesesteak, though the preparation and texture are different due to the "chopping" of the meat on the grill.
