In a container with a lid, whisk together the rice vinegar, soy sauce, olive oil, and pesto until well combined.
Add the mozzarella slices, turning to coat. Cover and marinate in the fridge for at least 1 hour, flipping the slices occasionally so all sides soak up the marinade.
Take the cheese slices out of the marinade and arrange them on a serving plate.
Place one olive half (rounded side up) on each mozzarella slice to look like an eyeball. Serve chilled.
