Cut tomatoes in half. Layer one piece of torn basil, 1 mozzarella ball, another piece of torn basil, and half a tomato (flat side facing down, so they can stand on their own) on a toothpick.. Repeat until all bites are made. Rub some of the remaining flavored oil that the mozzarella balls were packed in on the tomatoes to add some extra flavor. Add a sprinkling of sea salt if desired.
These make a great stand alone appetizer or can be added to an antipasta party platter.
