I'm with you on this one... I'll eat almost anything... Although I don't really care for organ meat.
Too many years traveling the world and learning about new cultures through their foods. Mmmm.
I managed a guy way back when that would only eat meat & potatoes, basically.
Whenever I wanted to give him a hard time, I'd tell him that he was coming to China/Malaysia/Thailand/... with my on my next trip.
His standard reply was "I'll be sure to stop for a fresh jar of peanut butter on the way home."
