In Northern Ireland and the United Kingdom, the food mainly consists of sandwiches and other savoury dishes. In Northern Ireland, the main dish is the bao bun, a popular street food that is considered by some to be one of the best sandwiches in the world. It is made from a special blend of flours and spices and is cooked by steaming or boiling. It is topped with meat, vegetables, and spices.

Bao Bun is available for both lunch and dinner. In the morning, it is sometimes served with pork, beef, or chicken lollipops, while in the evening, it is often served with beef, chicken, pork, or fish. It is also sometimes served with noodles or rice.

Bao Bun was first created in Northern Ireland. The recipe is said to have been invented by a Chinese restaurant called Fong Wing Palace.
