Bangers and mash, also known as sausages and mash, is a traditional British dish made of mashed potatoes and sausages, the latter of which may be one of a variety of flavoured sausage made of pork or beef or a Cumberland sausage. It is sometimes served with onion gravy, fried onions, baked beans and peas.
This dish may, even when cooked at home, be thought of as an example of pub grub — relatively quick and easy to make in large quantities. More up-market varieties, with exotic sausages and mashes, are sold in gastropubs, as well as less exotic alternatives being available in regular public houses.
Along with jellied eels and pie and mash, the dish has particular iconic significance as traditional British working-class dishes. In the north, black pudding and leeks have a similar reputation.
