If you are in Japan, you can buy these stuff at the vegetarian goods store in Kyoto.
If you are in the Philippines, you can check it out at Quan Yin Chay, Happy Veggie, and Tung Fang.
If you're somewhere else in the world, I saw some promising products at amazon like Butler Soy Curls, Betta Foods Imitation Chicken Chunks, and Bob's Red Mill TVP.
I'm sorry I haven't taken a photo of fresh soy protein in my local market. I don't usually buy it because my husband doesn't like it's taste. But the next time I'm not in a hurry doing the grocery, I'll make sure you get to see a photo of this. ^_~
Dried TVP Chunks
Commonly called TVP, meaning textured vegetable protein, this is a hard, tree-bark-like nuggets that needs to be soaked in warm water for ~20minutes or boiled for a few minutes to soften. You can flavor it however you want and it will give you a meaty texture to your dish. Just don't expect too much from it. It's not meat, so it don't be too hard on our TVP friends. They give a nice touch to some dishes, but I don't suggest putting it in all dishes as meat substitute. I personally don't appreciate it floating soggy in my soup. But it is really awesome barbecued.
Ground Soy Protein
Good in veggy meaty lasagna or spaghetti and so many other dishes, this may come as a textured vegetable protein, or a simpler soy protein. As soy proteins, it usually is the dried form of i think the soy bean byproducts when making soy milk or tofu. I don't know much about this, so if you do know, just comment them below. ^_~ thank you!
