I have never had one in a pie that I am aware of. I sure like them fried with a remoulade though.
Way back in HS a friend's family invited me to stay for dinner. They'd just slaughtered a hog (yes, in SoCal even) and were having fresh liver for dinner.
Mom came out after dinner with a pie and asked if I'd like a slice. I said of course. She said you don't even know what it is. I said "Mrs Brown, if you fixed it, it's probably good".
Then she told me it was a green tomato pie.
It was delish!
