The story behind the Slugburger dates back to the depression. Seems a local Mississippi butcher tried to stretch his meat by combining beef and pork, plus a filler, containing a few ingredients I’d probably rather not consider.  He shaped the meat into a patty, then deep fried it and served the combo on a bun with yellow mustard, onions and pickles. At the time the sandwich sold for a nickel, which carried the nickname– a slug. Thus, the birth of the slugburger still found in Corinth, Mississippi.
