I used about half the left-over smoked brisket from Sunday's BBQ, to make Philly Cheesesteak sandwiches. Charlie likes provolone and I like Cheese Whiz so I put in provolone in all of it, pushed some of it aside and added Cheese Whiz to my side and more provolone to his side. I'll make sure not to use a stainless steel skillet the next time I cook something with cheese in it. Clean-up was a chore.
