Cooking Instructions

1

Caramelize the Onions

In a skillet, heat olive oil over medium heat. Add sliced Spanish onion and a pinch of salt. Cook, stirring occasionally, until onions are golden brown and caramelized, about 15-20 minutes. Set aside.

2

Sauté the Mushrooms

In the same skillet, add the Shiitake, Baby Bella, and Button mushrooms. Drizzle with white truffle oil, and season with salt and pepper. Sauté over medium-high heat until mushrooms are tender and browned, approximately 8-10 minutes.

3

Assemble the Dish

Spread garlic mayo on the bottom of your choice of bread or bun. Layer the sautéed mushrooms and caramelized onions on top, then add Swiss cheese slices. If desired, toast the sandwich in the skillet until the cheese melts.
