I have to give props to Alton for adding the Philly Cheesesteak to his collection. However, a real cheeseteak uses American Cheese. I would skip wrapping the steak in aluminum foil, it will only get the roll soggy (unless you toast the roll first).

Don’t forget to slice open the roll half way so the top doesn’t come off the roll completely. After the meat cooks, pile it up in long rows, layer cheese over meat, and then put the roll over the meat so all you have to do is scoop up the meat into the roll in one motion. Let the roll sit over the meat for a few minutes to soften and toast it.
