The great Philly cheese steak. You've probably seen it on menus outside of Pennsylvania, but you have to go to Philadelphia to eat the real thing. There's a reason this sandwich is imitated around the world. Rib eye beef that has been sautéed then thinly chopped gets heaped onto a long, crusty roll. Cheez Whiz, provolone or white American cheese is then layered on top. This recipe features other flavors, too, including onion, green pepper and red pepper flakes. The steak doesn't take long to cook since it's sliced so thin. Simply pile it onto a Kaiser bun or Hoagie roll, and add the ingredients for the next best thing to an authentic Philly cheese steak sandwich.
