A few of the ones I've already got are:
I get all my protein right HERE, bitch!
The celery is stalking you.
You taste like chicken.
Vegans make the best lovers.
Eat this cookie with a peanut for a complete protein.
Note that I'm not looking to advocate here, but amuse. Vegan in-jokes are particularly welcome.
Also, if anyone has fortune cookie recipe advice beyond what is already in the tags, let me know. I was inspired by a bit in a fortune cookie factory on Food Network, and while their cookies were vegan, pretty much every online recipe contains eggs. I'll likely just Ener-G one of those, since the one vegan recipe I've seen doesn't feel quite right (and also calls for egg replacer, anyway).
I will be sure to post my (hopefully!) success story after.
