In a large bowl, stir together all of the tomatoes.
In a small jar with a tight-fitting jar, add the vinegar, oil, salt, pepper, and oregano, and garlic. Shake for 30 seconds.
Add the dressing to the tomatoes, only using as much dressing as you want. There may be dressing left over. Set the tomato salad aside for 15 minutes.
Plate the salad and top with a few mozzarella balls. Serve immediately.
