Marinade for the Seitan Corned “Beef”

  • In a large mixing bowl, mix all of the ingredients together until fully combined.
  • Slice 1 pound of seitan thinly. Place it in a large, shallow baking dish. Pour the marinade over the seitan and marinate in the refrigerator for 1 to 2 days.


  • In a small mixing bowl, whisk together all of the ingredients. Set a side.


  • In a large skillet over medium-high heat, warm the oil. Add the onion and peppers and saute for 7 to 9 minutes, until the onion is translucent. 
  • Remove from the heat and transfer the onion and peppers to a medium covered bowl. Set a side.
  • Place the sauerkraut in the skillet and return it to the heat. Warm it in the skillet for 5 minutes, until it is warmed through. Remove from the heat and transfer the sauerkraut to a medium bowl. Cover the bowl and set a side.
  • Toast the bread. Place the seitan Corned “Beef” in the skillet and return it to the heat. Warm it in the skillet for 5 to 7 minutes, until it is warmed through and a little brown on the edges. Remove from the heat and set a side.
  • Place 4 of the toasted bread slices on serving platter. Divide the Seitan Corned “Beef” evenly among the slices.
  • Atop each pile of Seitan Corned “Beef,” layer 1/4 of the sauerkraut, the pepper onion mix, the vegan mozzarella cheese, and the Thousand Island Sauce.
  • Top each Sandwich half with the remaining 4 slices of bread. Slice each sandwich in half and serve immediately.


MAKE IT BETTER: Simply marinade the seitan corned “beef” for 2 days and I assure you that it’s worth the wait. The taste will be amazing!
*BEET JUICE: Juice from a jar of pickled beets works fine.
**SEITAN NOTE: You can make the seitan yourself. Here’s the link for the homemade seitan.
