Soy flour turned into little chunks to give feeling of chunks in things you're used to having meat chunks in while being high in protein. So like burritos, stews, pasta sauce, stuff like that.

I had to look it up myself.

Textured or texturized vegetable protein (TVP), also known as textured soy protein (TSP), soy meat, or soya chunks, is a defatted soy flour product, a by-product of extracting soybean oil. It is often used as a meat analogue or meat extender. It is quick to cook, with a protein content comparable to some meats.

Where I live it is, because of local-ish soy production. Also helps that it's a complete protein, so you don't have to think as much about which amino acids you're getting from where.
