In a large bowl, combine the olive, vinegar, herbs, salt, and sugar. Add the tomatoes and toss to combine. Add more salt and pepper to taste. Chill at least an hour or until ready to serve.
Before serving toss together with mozzarella. Garnish with additional basil and drizzle with balsamic glaze if desired.
Notes
Fresh herbs are best but you can sub with dried. Just remember 1 tablespoon of fresh herbs is equal to 1 teaspoon of dried herbs.I like the taste of balsamic but it can turn the mozzarella balls dark which isn't very pretty. You can either use a white balsamic vinegar or toss in the balls at the last second before serving.A reduced balsamic glaze can be drizzled on top when ready to serve. This is sold by the regular balsamic. It's not necessary but it does dress up the dish.
