I'm half Chinese. That means I eat anything that twitches. And I eat ALL of the animal. Chicken feet (yummm!). Pig's trotters. Ducks' tongues (I kid you not!). If it moves, I'll eat it. But also, very little of the animal is wasted -- almost all of it is edible as far as the Chinese are concerned.
That said, some of the most delicious food I have tasted are vegetarian meals cooked by Buddhist monks.
