I have a fantastic recipe that I use for both Christmas and Thanksgiving. It's a bit long, but if it interests you I'll send it to you - basically it's seitan (or wheat meat or whatever it's called where you are) covered in gravy, then covered in a layer of stuffing, then in a layer of puff pastry. It can be shaped like a turkey if you want (I don't bother) or made into an oval. It's very attractive and really makes a centerpiece, which is what I was missing. I've been using it for over 15 years now
The other option is to stuff a pumpkin with whatever you like (my original recipe has some kind of rice dish inside) and bake it whole. It turns to a bright green, and the flesh is edible! It's also beautiful.
