Ate lunch late today.  Decided to swing by Penn Station and see if I would have success there. Tried their Italian Sub (SMALL). The sandwich taste was amazing.  I typically do not want to go with this many calories within a single sitting. Here is the breakdown:

Bread – 260 Calories
Ham – 33 Calories
Salami – 120 Calories
Pepperoni – 140 Calories
Provel Cheese – 100 Calories
Spicy Mustard – 50 Calories
Grand Total: 703

My suggestion would be to try the sandwich without Pepperoni, though I beleive that is the meat that gives the sandwich an amazing taste.
