I've been wanting to try this forever, and just happened to stumble upon a bag of TVP at one of the local Mexican grocery stores. I bought a pound of italian sausage-flavored ground turkey and added it to a cup of the TVP and the water. I also added spinach and a few spices; it just finished simmering and tastes really good! I have to head out soon so I'll be putting it in a container for the fridge once it cools, and I'll probably do the freezing method in a ziploc bag after I get home.
It would probably be amazing with a little spaghetti . . .
