Vegan Seitan Fajitas

This is a great summer meal – easy to make, and fun to eat. Marinate the seitan at least 2 hours in advance, if possible, and throw the rest together shortly before you are ready to eat. Though the prep time is long, active cooking time is actually very short.

About seitan: Seitan is a wonderful, vegan protein source, made from wheat gluten. It is high in protein, low in carbs and fat, and has a chewy, meaty texture. Like tofu, seitan has little flavor of its own, and is very versatile, as it takes on the flavors of its seasonings.
