Slice the tomatoes and bocconcini balls into thick slices (about 1/4" thick). I use roughly 15 slices of each for my salad, but you can make this salad as big or as small as you like by simply increasing or decreasing how many slices you use.
To a small plate, add a slice of tomato then add a slice of bocconcini overlapping the tomato. Continue layering the tomato and bocconcini, alternating the slices, until you have filled your plate.
Tuck basil leaves in between the layers wherever you think looks pretty. I used roughly 15 basil leaves.
Finish the salad by drizzling with olive oil, and balsamic glaze, and sprinkling with salt and pepper to taste.
Notes
Oil-free: for an oil-free version, simply omit the oil.
