What is bubble and squeak?

Like bangers and mash, bubble and squeak is British comfort food, a homey dish made from a mixture of mashed potatoes and chopped cooked cabbage that's fried until golden.
Bubble and squeak was traditionally a way to use up leftover meat from the requisite English Sunday roast, with the meat added to the mixture. But now it's usually made without meat. It is similar to the Irish dish Colcannon.
Bubble and squeak's colorful name apparently refers to the sounds it makes as it cooks -- or lands in your stomach.
