Bubble and squeak

Bubble and squeak is a traditional English dish: the shallow-fried leftover vegetables from a roast dinner[?]. The chief ingredients are potato and cabbage, but carrots, peas, brussels sprouts[?], and other vegetables can be added. It is traditionally served with cold meat from the Sunday joint, and pickles. The name is a description of the action and sound made during the cooking process.

A prepared frozen version is available.

To make bubble and squeak, start by frying a chopped onion in fat or oil. Chop the vegetables (which will have been boiled the previous day) together, and add to the pan. Cook over a medium heat till the underside is golden brown and crispy, then turn it, scraping the crispy bits into the mix. Repeat the alternate cooking and scraping a few times, then serve.

The name bubble and squeak is used in (at least) South East England - it is also Cockney rhyming slang for "Greek". The dish is also referred to as bubble and scrape in other parts (which?) of the country.
