Chiffonade a few leaves of basil
Quarter, slice, and seed 1 large tomato per serving
Grate some mozzarella cheese
Mix all ingredients together with salt, pepper, olive oil and balsalmic vinegar to taste.
Alternatively you could slice the tomatoes into circles, top with slices of mozzarella, sprinkle on basil, and drizzle with olive oil and balsalmic, for a more elegant presentation (but harder to eat)
