The nilly sandy is one of the tastiest morsels/snacks ever created. Created by placing anything between two vanilla waffers to create a sandwich effect. Reccomended fillings include fudge, peanut butter, jelly, chocolate, icing, and even more nillies (ie. the double and triple nilly sandy).
Dude, can you fix me up a nilly sandy, I've been hankering all day for a tasty treat.
