In a bowl, combine olive oil, balsamic vinegar, a pinch of dried basil, salt, and pepper. Mix well.

Cut the cherry tomatoes in half and hollow them out.

Insert the mozzarella balls into the hollowed-out cherry tomatoes and skewer them onto toothpicks.

Make a small hole in each mozzarella ball and fill it with a bit of the seasoned olive oil mixture. Place them on a serving plate. Before eating, remove the peppercorn.
