i would bring something to share with everyone.
but if you want to do a single serving thing, i think stuffed squash would work really well.
I can do that, too, but I'm worried that might seem rude. I haven't quite figured out the social mores over here. I'm down with bringing something that's not technically single-serve and that others can eat, but no one probably will. Leftovers for me.
I'm just at a loss for something to make. I have things to make seitan.
