I might have misspelled it. Seitain...something...I usually call it satan. It's basically the wheat version of tofu. Concentrated wheat protein. It makes a good fake meat substance. If you go totally veggie someday, you ought to try more tofu and seitain. Legumes do have protein, but you need to eat a lot of them to make up for what you miss in meat. Consider, 1/2 cup of great northern beans = 8 g protein. Only 1/4 cup tuna fish = 14 g protein. Plus, the beans are a carbohydrate, if you pay attention to carb counting (they are a good carb though, low on the glycemic index). It's been a long time since I looked at tofu or seitain but I'm pretty sure it packs in a denser amount of protein per serving, closer to actually eating meat.
