A sandwich made of very thinly sliced steak covered in melted cheese(american/whiz/provolone) served on a long hoagie/sub roll--usually with grilled onions. The cheese steak invented in the 1930's in Philadelphia by Pat Oliveri of the world famous Pat's Steaks located in South Philadelphia.
In the original movie, "Rocky" can be seeneating a cheese steak at Pats.
One of the best sub-foods in the U.S. A real Philly Steak is normally extremely greasy, it taste real good even if it may drip grease. Not like the dumbass definitions other people put. This sub, obviously, originates from Philidelphia.
The Only Place to get a cheesesteak worthy of the name is in philadelphia, The best are Geno's and Pat's wich are located in south Philly, a cheesesteak is a Amoroso hoagie roll with chip steak and either provolone, american, or cheese wiz, some peoplelike fried onions or peppers but they are not included in a true cheesesteak. NOTE: the term "philly cheesesteak" usally means the cheesesteak is not a true cheesesteak, also cheesesteak has no hyphen between cheese and steak
ya'll honky muthafuckas dontknow shit about cheesesteaks
