Is that a euphemism for "lettuce"? Or do you have concrete suggestions?
[I must admit that I have been completely uninterested in the paleo-diet, so I have not researched how it can be made vegetarian friendly. My usual food to bring to potlucks is along the lines of veggie chow mein, which I understand is not paleo-friendly...]
I eat vegetarian paleo myself, so I can think of stuff. I eat lots of cheese, butter, coconut oil, eggs, vegetables, and tubers. I also don't avoid soaked and fermented rice and legumes. I also approve of very dark chocolate.
Shannon and I are going to be hosting South Bay Less Wrong meetups at the Tortuga community in Mountain View on Thursday nights starting at 7. Come prepared to reveal something you're consistently irrational about. We'll spend some time throwing ideas around and then hang out and mingle.
Bringing paleo-friendly food is a bonus but not required.
If you'd like to come, request an invitation from our google group, Tortuga Rationalists.
