Your hubby and I would have similar items on our plates. Should I share the time I had green beans and pumpkin pie for Thanksgiving dinner? As a long-time vegetarian who generally dislikes Thanksgiving foods, here's my suggestion.
The best Thanksgiving dish I had that I enjoyed for the FOOD as opposed to the company was the rice stuffing in the Tofurkey turkey dinner package. The Tofurkey itself I could take or leave, but the stuffing was really good. And I detest the traditional bread stuffing. (Apparently, the tofurkey stuffing they make now has both bread and rice. I'm very disappointed.)
Unfortunately, I haven't had a whole lot of luck finding a recipe for it. Here's a possibility, though (sub vegetable broth, of course, and I'd probably leave out the mushrooms since I only eat those if I can't tell they're in the dish - broccoli makes a good colorful substitute):
Stuffed squash is another quasi-traditional vegetarian option: http://allrecipes.com/Recipe/Wild-Ri...sh/Detail.aspx
I'm sometimes tempted to go completely un-traditional and make a risotto (yummy) or lasagna or enchiladas or something like that. I am never sure whether traditional foods or the idea of FEASTING should win out. Personally, I think a feasting holiday where I fast really stinks.
