Add all vinaigrette ingredients to a mason jar and secure lid. Shake vigorously to combine. Set aside until ready to add to salad. (You will need to shake again before pouring)
Gently combine all of the remaining ingredients in a large bowl (careful not to break up the mozzarella too much). Pour dressing over top, and toss to coat. Place in refrigerator at least 30 minutes. If stored in a sealed container can sit in refrigerator up to 3 days.
