# What You'll Need:
→ Vegetables
01 - 1 cup cremini or white button mushrooms, cleaned and sliced
02 - 1 small shallot, finely chopped
03 - 1 clove garlic, minced
→ Dairy
04 - 4 slices Swiss cheese
05 - 2 tablespoons unsalted butter, softened, plus additional for sautéing
→ Bread
06 - 4 slices rye bread
→ Seasonings
07 - 1 tablespoon olive oil
08 - Salt and black pepper to taste
09 - 1 teaspoon fresh thyme leaves, optional
# How to Make It:
01 - Heat olive oil and 1 tablespoon butter in a skillet over medium heat. Add shallot and sauté for 1 minute until softened.
02 - Add mushrooms and cook, stirring occasionally, for 5 to 7 minutes until golden and any liquid has evaporated. Stir in garlic and thyme; cook for 1 minute. Season with salt and black pepper. Remove from heat and set aside.
03 - Lay out rye bread slices. Place one slice of Swiss cheese on two of the bread slices. Spoon the mushroom mixture evenly over the cheese, then top with another slice of Swiss cheese. Cover with the remaining bread slices.
04 - Spread softened butter evenly on the outside of each sandwich.
05 - Wipe out the skillet and return to medium-low heat. Add sandwiches and cook 3 to 4 minutes per side until bread is golden brown and cheese is fully melted, pressing gently with a spatula as needed.
06 - Slice each sandwich diagonally and serve immediately while warm.
