If you can find some TVP in the shape of a steak, that stuff is also insane to me.
Like, I'm kind of not qualified to actually compare it to a steak, but my body instantly gave me that vegetarian gag reflex when I first had it, because it has that same chewiness.

And yeah, it's really cheap. You can just have it in your cupboard for an eternity. And to prepare it, you just boil it in salt water / stock for a few minutes, press out the water and throw it into a hot pan to sear it like a steak.
The Maillard reaction does its thing and somehow this chunk of goddamn defatted soy beans does not taste healthy anymore.
