Preheat the oven broiler.
Place the slices of tomato onto a parchment lined baking sheet. Top tomato slices with BelGioioso Fresh Mozzarella and a sprinkle of grated BelGioioso Parmesan. Broil until cheese is melted and tomatoes start to caramelize. Remove from oven and let cool a minute. Garnish with fresh basil and serve as an appetizer, side or salad topper.
