Bread made of wheat gluten called ' Fu '

I was given a gift, which is called Fu in Japanese. It's been one of the Japanese traditional ingredient food but had been imported from China for almost a thousand.
It's wheat and gluten bread,as you know, very healthy food as well as Tofu, which is made from soy beans.
We often eat them at the memorial ceremony only with grain and vegetables without meat. Especially at the meal after funerals and memorial services.

I'm going to cook with Fu and planning to make imitation pork and rice ball.
People who like to cook with Fu told me it's very delicious like real pork cutlet.
I will try to cook imitation pork and rice ball  using Fu instead of pork for dinner.
