first cover the tvp with boiling water and set it aside. this is super important; it'll absorb a lot of water. I usually let it soak for 5-10 minutes and then drain it (lightly, that is, don't press out excess liquid)
I used to make a pizza sauce with it...who has time to make pizza anymore!!!
sautee some onions and garlic with a bunch of oil, toss in the spices you like (basil, oregano?), add green peppers; when all the sauteed stuff is soft, add the pre-soaked tvp. Keep sauteeing it, like you're browning it. When it starts to get brown, add tomatoe sauce, or sometimes i would use premade pasta sauce. If you don't use much tomatoe sauce, and you add say some garlic powder, this can be good for the meat part of a shepherd's pie.
I also have been known to use tvp in soup-- if the soup broth is nicely flavorful, tossing in a small handfull of tvp can be interesting.
