Thanks everyone for all of the suggestions. That cake recipe is something that I'll have to try.
We've decided to go "semi-vegan," because we have a friend that is in need and he is not vegan. Therefore, I'm going to make his absolute, favorite dish: Arroz con Camarones, or shrimp with rice. I am going to do all of the sides vegan except for the pumpkin pie. He'll get his very, own pie. I am resisting my husband's suggestion that he come to our house to eat, because of the covid thing, but I'm going to make him up a giant, care package and have the DH deliver it to him. I'm including a card to explain why we can't all be together and to wish him thanks for his friendship.
Some of the vegan sides are:
mashed potatoes
mushroom gravy
stuffing
rolls
cranberries
None of these really go with Arroz con Camarones, but it will all be good, non the less.
