Every toasty warm sandwich on the Potbelly Sandwich Shop menu is made to order. Choose between multigrain wheat or regular bread. Choose Originals (the "regular" size since 1977) or Bigs (30% bigger). Either one can be ordered on "Thin Cut" bread (1/3 less bread). Toppings: add Mayo, Mustard, Hot Peppers, Lettuce, Onion, Tomato, Pickle, Oil and Italian seasoning - or don't. It's up to you to make your sandwich the way you like it.
