This hearty Roasted Seitan, Peppers, and Portobellos dish is super easy to throw together, yet festive enough for special occasions. Recipe adapted from Vegan Holiday Kitchen.
In a large mixing bowl, combine the seitan, bell peppers, zucchinis, olive oil, and teriyaki marinade. Stir together. Transfer to a roasting pan.
Roast in the oven for 15 minutes, stirring occasionally. Stir in the scallions, then roast for 5 to 10 minutes longer or until the seitan and vegetables have a few charred spots.
Transfer the mixture to a serving container. Season to taste with pepper and optional dried hot red pepper flakes. Sprinkle with parsley and keep covered until serving.
