Cheez Wiz in a number 10 can that is on a grill being warmed to soften it has a paint stick in it to slather on a steak sandwich. There is also a roast pork sandwich with broccolirobs on it with or without provolone cheese. The cheese could be lunchmeat style on the roll or naturally sharp that you nibble on. Not sold everywhere. Tony Luke's sandwich franchise and D'Nics in the Reading Terminal are places that sell it. There are more.
