Olive loaf is a type of meatloaf or cold cut embedded with pimento-stuffed green olives similar to the Italian sausage meat mortadella. The deli meat—typically a mixture of beef and pork, though chicken has been used by meat producers such as Oscar Mayer — is often made by mixing green olives into milk powder before mixing it into the meat with spices such as mace, coriander and pepper. Green olives are typically the olives used in the loaf, as black olives would tend to bleed into the meat. In some cases, the meat mixture thickened with additives like milk powder and soy flour to prevent the olives from sinking. It is often sold in loaf-shaped sets.
