Bologna sausage (pronounce /boˈloʊni/) is an American sausage somewhat similar to the Italian mortadella, (a finely hashed/ground pork sausage containing cubes of lard that originated in the Italian city of Bologna). US Government regulations require American bologna to be finely ground, and it does not contain visible pieces of fat. Bologna can alternatively be made out of chicken, turkey, beef, or pork. It is commonly called bologna and often pronounced and/or spelled baloney. The "baloney" pronunciation can be used to mean "lies" and/or to express disbelief.
