Non-Kosher Subs are a type of sandwich that is not considered to be kosher according to Jewish dietary laws. The term 'SCABS' is an acronym for 'Substitute Cuts of Animal Belly Skin, ' which is the main ingredient in these sandwiches. Non-Kosher Subs are typically made with pork belly, bacon, and other processed meats, and are served on a bun or roll. They are popular in some parts of the United States, particularly in the South, and are often served as a quick and easy meal.
