Corned beef hash

Hash is a dish consisting of chopped meat, potatoes, and fried onions. The name is derived from French: hacher, meaning 'to chop'. It originated as a way to use up leftovers. In the U.S. by the 1860s, a cheap restaurant was called a "hash house" or "hashery." Canned corned beef hash became especially popular in countries such as Britain and France during and after the Second World War as rationing limited the availability of fresh meat. Hash may be served for breakfast, lunch, or supper. When served for breakfast in the United States hash may come with eggs, toast, hollandaise sauce, or baked beans.
