My contribution to this year's Thanksgiving dinner this year will be a) my now-traditional chocolate mousse and b) some kind of vegetable side dish that is not squash (because someone else has squash covered). My initial inclination is to do green beans, because I like them, but I have half a mind to do try something new that I haven't made before. Do you have a favorite Thanksgiving side dish that is: a) based on a vegetable that is not squash. b) can be made ahead or at the very least can be prepped ahead and just needs to finish cooking on site?
Bonus points if you've successfully fed it to children and/or picky eaters.
