Peel the mango, remove the seed and slice into 12 wedges. Set these aside. On a clean cutting board, place one slice of prosciutto, one wedge of mango and roll. Place a couple of fresh basil leaves on top and then a slice or chunk of cheese. Secure this with a toothpick. Drizzle just a bit of balsamic vinegar and sprinkle with some freshly ground black pepper. Serve as an appetizer or snack. Makes 12 appetizers.
