Last year, an appetizer of the sage crock 'cheese' from vegan vittles served with crackers and sliced apples was a hit with my family while we played a board game before dinner. I might add a pomegranate this year, they're fun.
Last year I made the pumpkin baked ziti from V'con with my (very much not vegan) friend's cranberry-pear sauce recipe, (which happens to be vegan http://seanan-mcguire.livejournal.com/59421.html#cutid1
). We had that with chipotle mashed sweet potatoes, a beet and arugula salad with satsuma mandarins and spicy candied pecans, sparkling cider, and pumpkin oat cookies.
I think I may reprise most of that this year, because it was low-stress and awesome, and everyone loved it, even the picky kid. I'm contemplating an apple-spice cupcake with lemon-'cream cheese' icing for dessert, though I also kind of like to make the gingerbread cupcakes from VCTOTW as a sort of 'welcome to the holiday season' treat. And my husband really, really loves pie, so maybe I should make a pie instead.
