1. On a lightly floured surface, roll out pastry to a 12-in. circle. Transfer to a 14-inch pizza pan; prick with a fork. Bake at 450 for 6-8 minutes or until golden brown. Cool on a wire rack.
2. In a saucepan, combine the water and pudding mix until smooth. Bring to a boil over medium heat, stirring constantly. Whisk in gelatin; cook and stir 1 minute longer or until thickened. Remove from the heat and let cool.
3. In a small mixing bowl, beat cream cheese and sugar substitute until smooth; fold in whipped topping. Spread cream cheese mixture over crust to within 1/2 inch of edges. Spread gelatin mixture evenly over cream cheese mixture. Arrange fruit over top. Refrigerate for 1 hour or until chilled. Refrigerate leftovers.
