Personally, I'd make a few large crock-pot batches of soups, chilis, and stews and freeze them in smaller containers.
Unless you're in the southern hemisphere (or in a very lucky location in the northern one!), it'll still be cold and wintery and I love soups in that weather! (Plus, they work whether you're feeling well, or even feeling ill.)
I also do things like spend a day making a MILLION vegan spanakopita triangles (or other freezable appetizer-type food). I assemble them and then freeze them on cookie sheets covered with tin foil. Then, in the case of an unexpected gathering, they can go straight from the freezer to the oven and feed a crowd with no prep work... Or I can pull a few off for myself if it's just me, and cook them separately.
I'd also google around for vegan OAMC (Once A Month Cooking) recipes since they will be easy to freeze and will likely have tried-and-tested directions for thawing and cooking.
Congratulations, and good luck!
