A chopped cheese sandwich is a type of deli sandwich that originated in New York City in the 1970s. It is made with ground beef, cheese, and onions, and is typically served on a hero roll. The sandwich is popular in bodegas and delis throughout the city, and has become a staple of New York City cuisine.
The chopped cheese sandwich is made by first browning ground beef in a pan. Once the beef is cooked, it is chopped into small pieces. The cheese is then added to the pan and melted. Onions are also added to the pan and cooked until they are softened. The beef, cheese, and onions are then combined and placed on a hero roll. The sandwich can be served with additional toppings, such as lettuce, tomato, and pickles.
