am so sorryabout what you are going through, I am not fully au fait with total veganism but I do make a winter veg casserole-------
chop roughly into squares---parsnips/carrots/leeks/swedes/turnips/potatoes[perhaps sl bigger]celery and any other root type veg you want , fry these until sl browned then put into casserole and coat with plain flour, add 2 thyme sprigs then cover with veg stock---but don't drown asthe veg will produce liquid of their own,season and add a good squeezeof lemon juice and cook moderate oven for about 2 hours or done--not mushy.
when done I serve with grated cheese---p'haps you have alternative? and eat with brown bread, very filling and comforting ------------enjoy!!
PS Ialso make mushroom stroganoff, maybe you could adapt this?????
