We also did bbq with friends and spent 8 hours smashing egghea---er, wizards in a dungeon (yes, I'm a D&D geek).
I made cheezy wizard brai--- er, macaroni. Used a traditional bechamel based (flour roux thickened) cheese sauce, but even thinned the mac still soaked most of it up... still looking for a way to keep it creamy (without using cream of mushroom soup). Still, it was cheesy.
