Cheesesteak

Philadelphia cheese steak, aka Philly cheese steak or simply cheesesteak (so named due to its origin in Philadelphia) is a sandwich often meeting the following criteria:

It is made with a submarine or Hoagie roll (an oblong, typically 6" or 12" piece of latitudinally-sliced French or Italian bread)
It contains a thinly-sliced, grilled piece of steak; Swiss, provolone cheese, or cheese spread such as cheese wiz; and possibly other ingredients including grilled onions, green peppers, mushrooms, and/or pizza sauce (a Pizza Steak). The cheese can be of many variates: provolone, American, or even cheese whiz!

The Inventor of the cheesesteak was Philadelphian Pat Olivieri who married chopped up steak to bun and with a little onions, began selling the new confections at his hot dog stand. They became so popular he opened up his own cheesteak restaurant in [1930].

Much debate can be had in Philadelphia over what makes a Philadelphia cheese steak unique. Some citizens believe it is the roll while others believe how fine the meat is chopped yet others believe it is the cooking method.

"Philly cheesesteaks" can be found throughout the U.S. and Canada at various sandwich restaurants, some of which specialize in or serve only cheesesteaks.

Pat's steaks and Geno's steaks, both in South Philadelphia on the same street, are widely considered the best places to get a cheesesteak anywhere.
