1 cup gouda cheese shredded

Instructions

Preheat the oven to 400°F (200°C).
On a baking sheet, toss the sliced mushrooms and onion with olive oil, salt, and pepper. Make sure they are well coated. Bake them in the oven for about 20 minutes until they’re golden and tender.
In a skillet, melt 4 tablespoons of butter over medium heat.
Assemble your sandwiches. Start with one slice of bread, add a layer of gouda, then pile on the roasted mushrooms and onions, followed by another sprinkle of gouda. Top with another slice of bread.
Coat each side of the sandwiches in the melted butter from the skillet.
Grill the sandwiches for about 2 minutes on one side. Carefully flip and cook for another 2-3 minutes until the bread is golden brown and the cheese is melting.
