That is too general of a question in my personal opinion. So instead of giving you just one, I’m going to break it down into categories, you can do as you wish with them.
My favorite cold cut style sandwich is a true Italian sub. The capicola, salami, sopressata, with fresh mozzarella, lettuce, roasted peppers with balsamic vinegar and real extra virgin olive oil.
My favorite hot sandwich is a tie for me. It’s between the classic cheesesteak freshly shaved rib-eye chopped up with fried onions with and ONLY with Cooper sharp cheese on a classic semolina hoagie roll. The tie is with an old school Italian classic with a new age twist. It’s a chicken parm hero on a toasted Italian roll, but instead of regular red sauce you use vodka sauce. It takes it to a whole different level. But the chicken has to be thin and layered with sauce in between each layer.
