Thank you for all your ideas and help!
I ended up buying a ham and a leg of lamb. The ham went into the crock pot with 1 cup of water and about 3 cups of frozen pineapple chunks. I carved the ham down to fit into the crock pot. the leg of lamb ended up in a Dutch cast iron pot on the stove. the ham was maybe not all the way warm and the lamb maybe a bit over done but not bad and no one complained. The kids are eating their candy right now and the adults are setting up for a family picture.
