In a small mixing bowl, whisk together white balsamic vinegar and olive oil. Season with salt and pepper. Set aside.

In a large mixing bowl, combine the bocconcini, halved cherry tomatoes, and blueberries. Gently fold to combine.

Drizzle the dressing over the salad and toss lightly to coat.

Tear fresh basil leaves and scatter them over the top just before serving.

Transfer to a serving platter and serve immediately.
