Bologna sausage is a type of processed meat that originated in Italy, named after the city of Bologna. It is typically made from finely ground pork, beef, or a combination of meats, along with spices and flavorings. The mixture is then stuffed into casings and cooked, resulting in a smooth texture and mild flavor. In the United States, bologna is often served as a cold cut in sandwiches, commonly paired with mustard or mayonnaise. It is usually sold in round slices and can be found in various forms, including beef bologna and turkey bologna, catering to different dietary preferences.
