Hash

About hashes
A hash is a dish of finely chopped meat (roast beef, pork and corned beef are the most common), potatoes and seasonings, usually fried together until lightly browned. Other chopped vegetables, such as green pepper, celery and onion, can also be added. Hash is sometimes served with gravy or sauce.

Hash is often thought of as a dish that you throw into it whatever is left in the kitchen. In the 19th century, cheap restaurants were called "hash houses" and the workers in these restaurants were called "hash slingers."
