Philly cheesesteak anyone

Most of them do use cheese whiz up in Philly..I use seared ribeye cut up on artesian bun with fresh boars head provolone....brazilian dry rub reverse sear to be exact....it makes it marvelous...oils,peppers,onions,shrooms......wtf
Never Ever seen any place in Philly that would use that stuff!! (cheese whiz) LOL
