What is "slugburger"

A slugburger (originally Weeksburger) is a traditional Southern food found in the area of Northeast Mississippi, particularly Corinth, New Albany, Booneville, Iuka, Tishomingo, Burnsville, West Tennessee, and northwest Alabama. Consisting of a patty made from a mixture of beef or pork and an inexpensive extender such as soybeans, it is deep fried in oil. It is typically served on a bun with mustard, pickles, onion, and in some places with a side of French fries or onion rings.
