Make a balsamic reduction. Pour the balsamic vinegar in a saucepan and turn on medium high heat. Bring the balsamic to a boil then lower to a gentle simmer. Let the balsamic reduce by almost half. This should take 16-20 minutes. Stir every few minutes to make sure it does not burn. The glaze will coat the back of a spoon when it is ready. Once done, set aside to cool.
On a large platter, layer the tomatoes, peaches and cheese slices to cover the entire platter. I like to do this on a circle or oval platter. You want the entire platter to be filled. Once done, go back with the fresh basil leaves and layer them throughout the peaches and tomatoes. I like to have them placed frequently throughout.
Drizzle the vegetables and fruit with the Colavita Extra Virgin Olive Oil. Then drizzle on 3-4 tablespoons of the balsamic reduction. You can use as much or as little of this as you would like. Sprinkle with salt and pepper.
