Italian beef / uh TALE yun beef / n. 1. Thinly sliced beef seasoned with garlic, oregano and other spices and served on Italian bread. A Chicago creation, it is slowly spreading nationwide thanks to transplants who can't do without it. The slow-cooked, top-butt meat can be eaten "dipped" (in beef broth), "sweet" (with sweet peppers), "hot" (with giardiniera), "cheesey" (with cheese) or as a combo (with an Italian sausage tucked beneath the beef). In Chicago, it's a source of pride, competition and dirty shirts. 2. A sandwich not known to be served anywhere in Italy.
