Bok choy is one of Tofu’s favourite vegetables. He always begins at the dark leafy end. If he gets lots of bok choy, he will only eat the leafy end of each leaf, leaving the lighter stems behind. But if given bok choy sparingly, he will finish the whole thing. Selective eating. People all over the world do it. So now I only give him a couple of leaves at a time. When he finishes leaf and stem, he can have more.
