Heat oven to 450°F. Make pie crust as directed on box for One-Crust Baked Shell using 9-inch glass pie pan. Bake 9 to 11 minutes or until light golden brown. Cool completely, about 30 minutes.
Meanwhile, in medium bowl, mix gelatin, sugar and boiling water until gelatin is dissolved.* Refrigerate until mixture just begins to thicken and get syrupy, 10 to 15 minutes.
Stir whipped topping into gelatin mixture until well blended. Fold in sliced strawberries. Spoon into cooled baked shell. Arrange strawberry halves around outer edge of pie. Refrigerate at least 2 hours or until serving time. Store in refrigerator.
