A dish made by dicing or chopping ingredients, typically potatoes and a cooked protein such as beef, pork, or corned beef, and pan-frying or sauteing them together until the exterior is crisp and the inside is tender. It likely dates to the 19th century as a way to use up leftover meat and vegetables, particularly in working-class households. In the American South it is often made with ham or sausage, while corned beef hash is the classic Northeastern U.S. version; the British dish bubble and squeak is related but distinct, made from mashed or fried potato with cabbage or other cooked vegetables rather than diced raw ingredients. It is a common breakfast item served with eggs, and also appears as a filling for breakfast sandwiches or a topping for eggs Benedict or burgers.
