For Philly you'd have to do Cheese Steaks.
Find an understanding butcher to thinly slice up some rib eye
Throw it on a flat top griddle, shredding it with 2 ,metal spatulas until there's no pink left.
Fry up some onions (optional) I personally don't like them.
Throw a Jar of Cheese Whiz in the microwave.
Get the best italian sandwich rolls you can find (most parts of the US this is going to be the hard part) and toast them up on same grill over meat.
Slap some of the cooked meat onto a roll with some whiz.
Serve ketchup, hot and sweet peppers, on the side;.
