Thanks for the feedback! Ok so to answer a few questions, I think they may be kosher. So this would make sense. But in that case, I have no problem if they say that - we keep a kosher house please don't mix meat/dairy etc..
I do not think she is providing a main course, we're all bringing stuff as far as I understand.
Plus, isn't vegan automatically dairy-free?? Sorry now I'm just being picky.
This is a party that has been put off/rescheduled for like 2.5mos so now everyone is now at the point where it's like, "let's get this over with" and we'll be bringing whatever she asks! It's an inconvenient day for me so probably not staying long anyway. And I'll bring flowers, lol along with something else. I have a vegan friend I can ask for easy/yummy ideas.
