Pulled pork is a do a couple a days head meat. That's so you can low and slow it, not worry about when its done. rest well and pull it. Add a little finishing sauce (I like Chef JJ's its totally awesome), and stick it in the fridge. Day of the party, drop the meat in the crock pot, adjust the taste (That means usually more of Chef JJ's finishing sauce), throw out some buns and some slaw and you are not tired, smelly, or stressed over when it will be done.
A little more formal, heat the Pulled pork back up and top a baked potato with it. Little butter and cheese on that tater first, then Pulled pork and some good hot BBQ sauce.
That would be my first thought.
Turkey would be my second thought, but its too close to Thanksgiving now.
You could cure a loin and have loin and fancy crackers for finger foods are needed, but that is about a 2 week ordeal.
Whatever you do, I am sure they will love it and appreciate the cook for smoking for them.
PS:: Only problem, you just hide the pulled pork in the reefer or someone will pick it all gone!
