Preheat oven to 450°.

Unroll dough into a 9-inch pie plate. Fold edges under and flute; pierce bottom and sides with a fork. Bake at 450° for 9 minutes or until lightly browned. Cool completely.

Meanwhile, combine strawberries and sugar in a medium bowl; toss well, and set aside.

Combine water, cornstarch, and lemon juice in a small saucepan, stirring until well blended. Bring to a boil, and cook 1 minute or until thick, stirring constantly. Add gelatin, stirring until gelatin dissolves. Pour over strawberries, stirring to coat. Pour into prepared crust. Cover and chill at least 3 hours. Top each serving with whipped topping.
