Eating Rocks?? A REAL dinner challenge to serve REAL food - PICA??

Well, this is a first.  I am just a couple months into my journey to eat REAL, and guess who is coming to dinner? One hint, it's not Sidney Poitier (if you think it's a challenge to me to cook a meal for one of this country's finest actors, you're nuts!). No, it's a cousin of a friend of mine who has PICA -http://en.wikipedia.org/wiki/Pica_(disorder).  Bottle gourds and backyard raised chickens won't cut it with this guy.  So here I am, looking up every recipe in a PICA cookbook and they all sounds disgusting.  How do you serve someone REAL food who doesn't eat food??

I will NOT serve crushed rocks or animal feces to anyone at my house. That is NOT hygienic. But what about dirt?  I will probably need to get my soil tested for hazardous substances, but I am thinking something like a "mud-pie". Why not? I mean the one dairy queen serves probably has more chemicals in it than the soil in my backyard.  I know this sounds crazy, but I would rather be thoughtful and respectful for my dinner guest and help him eat something healthy within his rather odd dietary restrictions.   Kosher, gluten-free, or PICA...I think these people all deserve access to REAL eating.

I am NOT condoning PICA, and if you think you suffer from PICA, please get help (maybe here http://www.allianceforeatingdisorders.com/pica).  But if you just can't help yourself, than at least eat safely! Wish me luck this Sat night. Have absolutely no clue what to do for beverages.
