In a small saucepan heat balsamic vinegar over medium low heat. Stir occasionally, for 15 minutes until vinegar has reduced to a half cup. Set aside to cool.
Assemble skewers, start with a basil leaf, then add a half slice of tomato, a bocconcini cheese ball and repeat.
Drizzle with balsamic reduction and add garnish before serving.
