The Schlotzsky's Hot Ham and Cheese Original sandwich features smoked ham layered into a triple melt of Cheddar, Mozzarella, and Parmesan, pressed with briny black olives and our creamy, tangy signature sauce into fresh-baked sourdough, toasted until the cheese locks in and the bread goes golden. Finished with crisp lettuce, ripe tomato, red onion, and yellow mustard. The hot ham and cheese sandwich done right.
