Using a large round platter, arrange the tomato slices and mozzarella in a repeating fashion, slightly overlapping them as you arrange around the platter. You can either place a single (or few) fresh basil leaves in between each tomato and mozzarella slice or place a few around the platter.

Drizzle with extra virgin olive oil and balsamic vinegar and sprinkle with a little salt if desired. Serve and enjoy!
