Seitan is a pseudo-Japanese word for the textured wheat gluten used as a meat substitute in many Asian countries and for those on a macrobiotic diet.
So be aware that you can't have anything with seitan in it if you're gluten-free, even if it's not specifically advertised as wheat. Seitan is popular with vegetarians and vegans, and that's for a reason: It contains tons of protein, which can be hard to get on a vegetarian/vegan diet. Since you obviously can't include seitan on your gluten-free vegetarian or vegan diet, you'll want to look for alternative sources of protein.
