The folks over at Huffington Post has assembled a list of 8 recipes for LEGO food items. To be clear, these are food that we can eat, and are created to look like LEGO items and not from LEGO items.
A lot of the items are aimed at kids for parties or to keep them from being bored, and most are sugary snacks. You could also serve these at your next LUG meeting or give them out to the AFOLs you know.
