Hot ham and Swiss with giardiniera on a sub roll. The best way to prepare a sammich of this sort is to lay the meat in a non stick skillet and cover it with the cheese, and then heat it slowly with a lid on. When the cheese is ready use a spatula to transfer it all to your bun. I spread butter on this roll and toasted it while the cheese was melting. Mustard and pickles are the classic garnishes for these but I really like the hot giardiniera – and I have a huge jar of it to get through!
