Using a sharp knife, carefully slice your tomatoes into 1/4-inch thick slices; then repeat the same with your mozzarella cheese.
Next, stack a tomato and a mozzarella slice, then wrap a thin slice of prosciutto over the stack. Repeat with the remaining ingredients and arrange them on a nice platter as shown.
Top with fresh basil leaves, then sprinkle with sea salt flakes and freshly ground black pepper. Immediately before serving, drizzle with olive oil and balsamic vinegar.
Enjoy!
