Preheat broiler to medium-high. Brush mushrooms with olive oil and sprinkle with salt and pepper. Broil mushrooms on both sides for 2-3 minutes until tender. Remove from broiler and top with a slice of BelGioioso Italico™ and sliced tomatoes. Return to broiler and heat until cheese is melted. Drizzle with a balsamic glaze and garnish with fresh basil.
Balsamic glaze: Place 2 cups balsamic vinegar into a saucepan over high heat. Reduce vinegar by half and allow to cool before using.
