Bánh mí  (or Saigon subs as they are called in America) are a kind of submarine sandwich, that might also be a rite of passage for a secret society. If you haven’t had one, you don’t know what I’m talking about, and if you have, you probably have buddies with whom you share your passion for this amazing dinner-sized, snack-priced foodie favorite. They are cheap, delicious and like no other sandwich.
