1Cook rice as directed on box. Refrigerate 10 minutes to cool.
2Meanwhile, cut thin slices from tops of tomatoes. Gently squeeze out and discard seeds. Using teaspoon, remove pulp from tomatoes, leaving 1/4-inch shell. Drain upside down on paper towels. Refrigerate until serving time.
3In medium bowl, mix rice, turkey, celery, bell pepper and onions. In small bowl, mix dressing ingredients. Pour dressing over salad; stir gently to coat. Cover; refrigerate until thoroughly chilled, at least 45 minutes.
