Method
 

Cooking Instructions
  1. In a large skillet, heat a mixture of olive oil and butter over low heat. Add sliced onions and sauté for 30-45 minutes until caramelized. Stir in brown sugar and balsamic vinegar; cook for an additional 2-3 minutes. Season with salt and pepper to taste.
  2. In the same skillet, add olive oil and heat over medium-high. Add sliced mushrooms and sauté for 8-10 minutes until browned. Add minced garlic and thyme; cook for 1 more minute. Deglaze the pan with white wine and let reduce for a couple of minutes.
  3. Take slices of sourdough bread and butter one side of each. Add a thin layer of Dijon mustard on the unbuttered side if desired. Layer half of the Swiss cheese, caramelized onions, and sautéed mushrooms on each slice. Top with remaining cheese.
  4. Heat skillet over medium-low and place sandwiches in, buttered side down. Cook for 3-5 minutes until golden brown, then flip and cover to melt cheese for another 3-5 minutes.
  5. Remove from skillet, slice in half, and serve warm.
