Method

Preparation Steps

  1. 1

    Caramelize Onions and Mushrooms

    In a skillet, melt 1 tablespoon of butter over medium heat. Add sliced onions and cook, stirring frequently, until they turn golden brown, about 10-15 minutes. Add sliced mushrooms, season with salt and pepper, and continue to cook for an additional 5-7 minutes until they are tender. Remove from heat and set aside.

  2. 2

    Prepare the Sandwich

    Spread a generous layer of Horseradish Dusseldorf Mayo on one side of each slice of bread. Layer one slice of Swiss cheese on top of the mayo on one slice of bread. Add the caramelized onions and mushrooms on top of the cheese, then place the second slice of Swiss cheese over the filling.

  3. 3

    Grill the Sandwich

    Heat the remaining tablespoon of butter in the skillet over medium heat. Place the sandwich in the skillet and cook until the bread is golden brown and the cheese is melted, about 3-4 minutes per side. Press down slightly with a spatula for even toasting.

  4. 4

    Serve

    Remove the sandwich from the skillet, cut in half, and serve immediately. Enjoy your W.A.S.P. sandwich!
