It tastes very sweet and is kind of fruity. There are many different flavors at work... the spices, tomatoes, bell pepper, onion... And with all the colors, it's a fun dish to look at.
For the seitan, I used Trader Joe's Beef-less Strips. I've never had much luck creating my own seitan. It always turns out kind of spongy. FYI, the TJ's strips are seitan, but they don't call them that. Seitan is made from vital wheat gluten and spices, and is very high in protein and fiber.
Ingredients: seitan, red onion, red or yellow bell pepper, zucchini, grape tomatoes, scallions, jalapeno, garlic, fresh ginger, soy sauce, cider vinegar, lime juice, dark brown sugar, thyme, allspice, cumin, nutmeg, fresh orange juice, black pepper, salt.
