Bangers and mash is a classic British dish that consists of sausages served with mashed potatoes and gravy. The sausages, or bangers, can be made from pork, beef, or a combination of both. They are typically pan-fried or grilled until golden and cooked through. The mashed potatoes are creamy and buttery, and the dish is often served with a rich onion gravy. Bangers and mash is a popular comfort food in the UK and can be found in many traditional British pubs.
