2 cups boiling water, divided
1 pkg. (4-serving size) JELL-O Brand Lime Flavor Sugar Free Low Calorie Gelatin
1/2 cup cold water

STIR 1 cup of the boiling water into dry lime gelatin mix in medium bowl at least 2 min. until completely dissolved. Stir in cold water. Refrigerate 45 min. or until slightly thickened (consistency of unbeaten egg whites). Stir in yogurt with wire whisk until well blended.
POUR into 2-qt. serving bowl. Refrigerate 15 min. or until gelatin mixture is set but not firm (gelatin should stick to finger when touched and should mound).

Add frozen strawberries; stir until strawberries are separated and gelatin is thickened (spoon drawn through leaves definite impression). Spoon over lime gelatin layer.
REFRIGERATE 2 hours or until firm. Top with the whipped topping. Store leftover dessert in refrigerator.
