Preheat oven to 400 degrees F. Unfold pastry on a lightly floured surface; roll lightly to remove folds. Cut in half lengthwise. Cut each piece crosswise into 5 2" wide rectangles, and place on baking sheet. Bake 12- 14 minutes or until golden; remove to wire rack to cool.
Beat pudding mix and sour cream at low speed with an electric mixer until thickened, about 2 minutes. Fold in whipped topping.
Split pastry rectangles in half horizontally. Spoon about 3 tablespoons filling into bottom of halves, and top with 2 tablespoons of filling. Cover with top; drizzle with remaining fruit filling.
