Fundamentally it has to be non toxic in the dose I am eating (everything is toxic if you eat too much). Will not fight me back when I am eating it (doesn't move anymore). I understand someone will eat live shrimp or fish but they must be not moving to me. No problem with head still on (in many places if you use an animal for sacrifice in ceremony its head need to be there so that's that) but I don't really care either way.
I'm not a big fan of organs, or rare meat other than sashimi, or anything too stinky (cheese or tofu or raw fish sauce or durian, not too stinky please). Mammal meat must be at least medium in steak standard.
I'm ok with baby octopus, fish head (the cheeks are the best if you guys don't eat head) although not excited about it. No balut for me and no brain of any animal. No chicken "butt" either. Thousand year old (lye marinated) egg I can tolerate but not a big fan of.
Nothing too expensive or hard to get. I'm fine with affordable non exotic everyday food.
