It seems everyone is suggesting ribeye, and that is a common ingredient, but a truly authentic Philadelphia cheesesteak uses top round sliced hair thin against the grain. The original idea behind the cheesesteake was to find a way to make a tough cut of meat tender enough to eat quickly without having to slow roast or slow braise it for a long period of time. The meat should be fried on a griddle, or whatever griddle-like frying utensil is available, over medium heat with salt and pepper, browned and then chopped into small pieces with the end of a spatula, and served with sauteed onions. As mentioned elsewhere in the thread, the roll is another key ingredient. A long, soft, Italian torpedo roll is necessary for authenticity. A proper roll can be even harder to find outside Philly than the proper cut of meat. If you can find amoroso's, use it. Otherwise, look 'em up on the interwebs to get an idea of what might make an acceptable substitute. And of course, and although American and Provolone are frequently used, for proper authenticity it's gotta be cheez whiz. Warmed Cheez Whiz, melted to the point of flowing, slathered over the top. And that's what it's all about. The rest is all fluff.
