A slug steak was a cut of flesh from the wooly slug, served as food in Ferengi culture. Slug steak was very popular until it was determined that it was a breeding ground for dangerous microbial parasites.

After the "Slugboy With No Name" demanded three tons of Grade A slug steaks from wealthy slug herder Nix in order to save his herd from the dreaded snailosaurus, he established a clothing line and gave away a free slug steak for every wooly slug sweater sold. (DS9 reference: Legends of the Ferengi)
