What Mississippi burger uses a beef patty mixed with cereal or crackers?

The Mississippi burger made with a beef patty mixed with cereal or crackers is the slugburger.

A slugburger combines ground beef with an inexpensive filler such as soybean meal, flour, or cereal. The mixture is shaped into a thin patty and fried, producing a crisp exterior and a distinctive texture.

The burger is especially associated with Corinth, Mississippi, and nearby parts of northeastern Mississippi and western Tennessee. Its origins are tied to the early 20th-century practice of stretching scarce meat supplies with inexpensive ingredients.

The name is historical slang and does not indicate that the sandwich contains slugs. One explanation connects “slug” with the five-cent token or coin once used to buy the burger. Modern versions may use different fillers, but the economical mixed patty remains the defining feature.
