Vinaigrette:
In a glass jar with a tight-fitting lid, add together all the ingredients. Seal tightly and shake to emulsify. Refrigerate until ready to use.
Salad:
Cook tortellini as directed on package. Drain and rinse with cold water to cool; shake off excess water.
In a large bowl, combine tortellini and mozzarella balls with enough vinaigrette to coat. Set aside 15-20 minutes for flavors to develop. In a separate bowl, combine mixed greens with 2-3 tablespoons of vinaigrette; toss to coat.
To assemble salad, add marinated tortellini, mozzarella balls, greens, and remaining salad ingredients to a large serving platter. Drizzle extra vinaigrette (if desired). Serve with prosciutto wrapped breadsticks. Enjoy!
