What about catering it? At five weeks post-op, I still have no interest in food, so being around it doesn't actually bother me. But I still don't like eating in restaurants yet...however, if your family wanted to eat out, you could go along and just get some butternut squash soup or something like that. I'm probably going to cook Thanksgiving dinner this year, but it will be simpler. But I should be able to eat most of the food, in teeny tiny portions, by then.
By Christmas, you will at least be able to eat some of the food, so don't worry about that one...
