Cut up all veggies & fruit and place in a large serving bowl. Cook bowtie pasta according to package (typically 12-15 minutes). Rinse and combine pasta with the fruit & veggies.
Stir together the yogurt, vinaigarette and sweetner in a small mixing bowl. Then add to the salad, a tablespoon or so at a time. Only add enough to cover the salad.
Cover and chill in the fridge until serving time.
