This is a bit unconventional, but Chinese flatbread goes really well with turkey(and is quite easy to make). This recipe seems fairly legit:

For additional filling, we usually also make shredded potato with chiles and vinegar(you can add carrots, too):

as well as various shredded raw or lightly boiled vegetables.
In any case, if you don't want to go the full Peking Duck route, the flatbread goes just as well with typical Thanksgiving food.
You could also try making a borscht, maybe? Perfect for the fall and fits right in with more traditional Thanksgiving dishes. I recommend making a separate beef stew first, letting that sit overnight, and only then starting the final product, instead of making the borscht all in one go. Not the most efficient way, to be fair, but I find that this makes the flavor much more intense.
