Grilled Cheese with Gouda, Roasted Mushrooms and Onions

Preheat oven to 400°F.

On a rimmed baking sheet toss sliced mushrooms and onion in olive oil. Sprinkle with a few pinches of salt and pepper. Bake in the preheated oven for about 20 minutes, or until roasted to your preference. When done remove pan from heat and set aside.

In a skillet over medium heat, melt 4 tablespoons butter.

While butter is melting, assemble sandwiches. On one slice of bread, layer 1/4 cup of shredded gouda, half of the roasted mushrooms and onions, then 1/4 cup of gouda. Layering this way ensures that the melty cheese will hold the sandwich together. Salt and pepper to taste. Top with another slice of bread and lightly press together. Set sandwich aside. Repeat this process to make the other sandwich.

Place the sandwiches into the skillet on top of the melted butter for one second, then gently flip them over to the other side. Cook for about 2 minutes, until lightly browned on the one side. Then gently flip sandwiches onto the other side and cook for an additional 2-3 minutes, or until cheese is melted and sandwich is browned to your preference. Plate the sandwiches and enjoy!
