Authentic Philly Cheesesteak is very thinly sliced ribeyes on amoroso rolls. Cheese it depends on who you talk too the 3 popular cheeses for Philly cheesesteaks are CheezWiz(The Wiz), Provolone, and American. Take your pic on which one you want to use. I personally like Cheez Wiz on my Cheesesteaks.
