For thanksgiving, I would like to do a side dish, for most of us, that can be a main dish for my vegan mother. I don't want want a soup, but something that can go on the plate along with the other sides for her, along with the turkey for us carnivores. Ideally something that can be made ahead, then heated for dinner. Whenever I do a google search, somehow "vegan" does not count. Lots of vegetarian dishes with cheese, etc. come up, as well as a few with meat.
Any suggestions?
