I know a few veggies who see nut roast in the same way as a badly cooked turkey as part of a rubbish tradition.
I rather like them.
+1 to just asking them what they prefer. If it were me I’d be happy with the veg and something simple like a couple of Quorn burgers, the absolute last thing I’d want is a lot of drama. I hate being the centre of attention when it comes to food and don’t want to be a monumental PITA to cook for.
Just be mindful of keeping Yorkies and veggies veggie, don’t roast them in lard and turkey juice. Oh, and veggie gravy of course, Bisto Best onion gravy is as close to regular gravy as I’ve found.
