Grilled cheese with gouda, roasted mushroom and onions. Roast mushrooms and onions with olive oil about 20 minutes. Layer shredded gouda on bread, then mushroom/onion mixture, then gouda. Top with bread and fry like grilled cheese.
Croque Monsieur is the French version of a toasted ham and cheese sandwich. As someone who loves grilled cheese, ham sandwiches, AND ham and cheese hot pockets, there is simply no way this can go wrong!
