Didn't know it existed

I had lunch with an old friend from high school today at the Atlanta Bread Company. While I've eaten there previously - the only dish I've had is their chili, which is usually very delectable, save for the time right before it closes - I've never really had any of the meals that sets the restaurant apart, for better or worse. In the end, I tried out their California Avocado sandwich, which turned out to be a nice light sandwich. I am a fan of avocados, as my girlfriend has correctly stated (not obsessed, though!), but I've never eaten them in anything other than guacamole or as individual slices in a salad. It never occurred to me that there was some other use for them.
