Take a Tip From Philadelphia
Philadelphians love steak sandwiches on torpedo-shaped Italian bread made from inexpensive, paper-thin sliced beef, usually lean round, sold as chip steak, sandwich steak, or wafer steak and often found in the freezer case. Harry Ochs shaves tender, lean, gristle-free beef round for his customers. Not in Philadelphia? No problem. You can approximate the technique. Simply freeze beef round until firm but not frozen (about 1 hour), then use the sharpest knife in your block (or a deli-style meat slicer) to shave off paper-thin slices, making sure to work across the grain.
