  • 1 teaspoon neutral flavored oil
  • 2 shallots thinly sliced
  • 16 ounces seitan sliced
  • ½ cup white wine
  • 1 cup vegetable stock
  • 2 tablespoons whole grain mustard
  • 2 tablespoons Dijon mustard
  • 2 tablespoons non-dairy milk
  • 1 tablespoon cornstarch
  • 1 teaspoon capers drained
  • ½ teaspoon sea salt
  • ½ teaspoon black pepper


  • Add the oil to a large pan over medium-high heat. Add the shallots and cook until until they begin to brown, 5-10 minutes.
  • Add the seitan to the pan and continue to cook, stirring often, for about 10 more minutes, until it begins to brown.
  • Pour the wine into the pan and deglaze any bits of shallot or seitan that might be stuck to the bottom. Allow the seitan to absorb the wine.
  • Whisk together the stock, mustards, non-dairy milk, cornstarch, capers, salt, and pepper. Add it to the mixture to the pan, and stir. Allow the sauce to heat throughout and thicken slightly. Remove from the heat.
  • Serve hot with potatoes or whole grains and greens.
