Creating the Swiss Mushroom Melt Sandwich is straightforward if you follow these simple steps:

1. Sauté Mushrooms: In a large skillet, heat olive oil over medium heat. Add the sliced mushrooms and cook until they are browned and tender, about 5-7 minutes.
2. Add Garlic: Stir in the minced garlic and cook for an additional 1-2 minutes until fragrant.
3. Season: Season the mushrooms with salt and pepper to taste. Remove from heat and set aside.
4. Prepare Bread: In another skillet or griddle, melt 1 tablespoon of butter over medium heat. Place two slices of bread in the skillet.
5. Add Cheese: Top each slice of bread with a slice of Swiss cheese.
6. Add Mushrooms: Spoon the sautéed mushrooms evenly over the cheese on both slices of bread.
7. Top with Cheese: Place another slice of Swiss cheese on top of the mushrooms.
8. Add Bread: Top with the remaining two slices of bread, pressing down gently.
9. Grill Sandwich: Cook until the bottom is golden brown, about 3-4 minutes. Carefully flip the sandwich and add the remaining butter to the skillet. Cook until the second side is golden and the cheese is melted, about another 3-4 minutes.
10. Slice and Serve: Remove from the skillet, slice the sandwich in half, and garnish with chopped parsley if desired.
