Is it the same as those dehydrated soy chunks? The ones that kind of look like kibble when dry? Or some other vegetable? I also have some meat replacement chunks in the freezer that came from the Chinese supermarket, they may be suitable as well. It looks delicious!
For the TVP I usually hydrate it in veggie stock, use a bit of soy sauce and vegan Worcestershire sauce and some spices including garlic powder, onion powder, smoked paprika, and maybe change it up a bit depending on the dish.
I've never heard of this being a thing. Do you know what causes it? I've never tried tvp and I kinda want to look into this before stocking up or anything
