Are Cheesesteaks Italian?

Around here, we have a ton of little pizza parlors; I can count at least 12 within three miles. They all offer pretty much the same fare. Pizza's of course. And hot and cold submarine sandwiches such as Italian heroes or meatball sandwiches or sausage with peppers and onions. Plus all the traditional pizza parlor dinners such as spaghetti and meatballs or veal parmigiana or fettuchinni alfredo. And cheesesteaks.

Cheesesteaks? Are they Italian? Did I miss something? Why do all these places have this on the menu? I never figured that cheesesteaks were even ethnic. And it may be the only thing on the menu that is cooked on the grill.

Maybe I missed a class or something.
