The Vito Sub at Jimmy John's
In my getting-less-humble opinion, this sub is the best sandwich on the menu of the best monster sandwich chain around. Jimmy John's is just solid stuff: the bread is fresh and great, the meats and cheeses are high quality, and they throw it together in a quick and classic way.
Speaking of classics, this Italian sub has a traditional meat mix of Genoa salami and just-spicy-enough capicola. (Actually, the cappy is a little sweet and a little spicy.) There's smooth provolone cheese, onions, tomatoes, shredded iceberg lettuce and a tangy vinaigrette to bring out the best in the veggies. Like most everything at Jimmy John's, I highly recommend you order the Vito with hot cherry peppers, which add a powerful vinegary kick. An Italian sub is a beautiful thing, and it's pretty good every time at Jimmy John's.
