IIRC you're a vegetarian (or maybe piscetarian... as in you'll eat fish too), are you not sharke? Cuz of the cancer stuff?
Personally I've found (after trying lotso stuff) that straight up legume protein is where it's at for me (beans, lentils, etc). A lot of the other stuff does something weird to my guts. Especially TVP (textured vegetable protein).
Polenta is pretty good though but expensive so I haven't had it in years. Tofu isn't too harsh on my system either but doesn't keep me full like legumey goodness does.
I do however save my meat drippings and toss it into my lentils, black beans, etc.
Just tastes better and I kind of need the extra fat.
Might make a big batch of lentil soup tomorrow and use the whack of pork chop/bacon leavings I have in my fridge to tart it up a bit.
