This hearty combination of seitan, bell peppers, and portabella mushrooms is so easy to throw together, yet makes a festive main dish for special occasions.
  • 2 pounds seitan, cut into bite-sized chunks (see note)
  • 1 red bell pepper, cut into wide strips
  • 1 yellow bell pepper, cut into wide strips
  • 2 medium-small zucchinis, sliced ½ inch thick
  • 8 to 10 ounces portobella mushrooms, stemmed and sliced
  • 2 tablespoons olive oil
  • ½ cup teriyaki marinade, store-bought or homemade
  • 3 to 4 scallions, thinly sliced
  • Freshly ground pepper to taste
  • Dried hot red pepper flakes to taste, optional
  • ¼ cup minced fresh parsley
  1. Preheat the oven to 400º F.
  2. In a large mixing bowl, combine the seitan, bell peppers, zucchinis, olive oil, and teriyaki marinade. Stir together. Transfer to a roasting pan.
  3. 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 are touched here and there with charred spots.
  4. 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.
