Which Wich, early lunch

For the past few days I've not had much in the way of normal food
because I've been rushing from one appointment to the next. So, today
is my first chance to eat normal food in a while. I've been surviving
on Clif bars for days. They taste good, and have plenty of nutrition,
and come in a wide variety of flavors, but now I'm really craving a
Which Wich sandwich.
