Ingredients

Method

Directions

  1. 1

    Caramelize the Onions

    Slice the large onion into thin strips. In a skillet, heat 1 tablespoon of butter or oil over medium heat. Add the onions and a pinch of salt. Cook, stirring occasionally, for about 15-20 minutes until the onions are golden brown and caramelized.

  2. 2

    Cook the Mushrooms

    While the onions are caramelizing, clean and slice the mushrooms. In another skillet, heat 1 tablespoon of butter or oil over medium heat. Add the mushrooms and sauté for about 5-7 minutes, or until they are tender. Season with salt and pepper to taste.

  3. 3

    Assemble the W.A.S.P.

    Take two slices of bread of your choice. Spread a generous amount of Horseradish Dusseldorf Mayo on one side of each slice. Layer the Swiss cheese on one slice, followed by the caramelized onions and sautéed mushrooms. Top with the other slice of bread, mayo side down.

  4. 4

    Grill the Sandwich

    Heat a skillet over medium heat and add a little butter or oil. Place the sandwich in the skillet and grill for 3-4 minutes on each side, or until the bread is golden brown and the cheese is melted.

  5. 5

    Serve

    Remove the sandwich from the skillet, slice it in half if desired, and serve hot with extra Horseradish Dusseldorf Mayo on the side.
