Rostbratwurst is a grilled sausage that originated in the Franconia region of Germany. It is made from finely minced pork, beef, or veal, and seasoned with a blend of spices such as marjoram, caraway, and garlic. Rostbratwurst is longer and thinner than the traditional bratwurst and is often served in a crusty roll with mustard and sauerkraut. It is a popular street food option in Munich.
