Delicious Mushroom and Cheese Grilled Sandwich: A Melt-In-Your-Mouth Delight

In a small skillet, melt 1 tablespoon of butter over medium heat.
Add the sliced mushrooms and sauté for 5-7 minutes, stirring occasionally until they are golden brown and tender.
Sprinkle with garlic powder, thyme (if using), salt, and pepper to taste. Set the mushrooms aside.
Assemble the Sandwich:

Butter one side of each slice of bread.
On the unbuttered side of one slice, layer the sautéed mushrooms and shredded cheese. Top with the second slice of bread, buttered side up.
Grill the Sandwich:

Heat a skillet or griddle over medium heat.
Place the sandwich in the skillet and grill for 3-4 minutes per side, or until the bread is golden and the cheese has melted.
Serve:

Remove the sandwich from the skillet and let it cool for a minute before slicing it in half. Serve hot, and enjoy the crispy, cheesy goodness!
