Provolone cheese

Provolone cheese is an Italian cheese, very similar to mozzarella cheese, which is traditionally used on submarine sandwiches. It is generally sliced into small, circular disks (similar to bologna), and used almost solely in sandwiches. It has a more distinct flavor than mozzarella; however, its taste is less enjoyed raw (unlike mozzarella).
