1Heat oven to 375ºF. Heat pie filling, cornstarch and orange peel to boiling in 2-quart saucepan over medium heat, stirring constantly. Gently stir in blueberries; remove from heat.
2Cover phyllo sheets with damp towel to prevent them from drying out. Fold each sheet lengthwise in half. Arrange sheets in a spoke pattern in 12-inch pizza pan or jelly roll pan, 15 1/2x10 1/2x1 inch, brushing each strip with butter as it is added and overlapping ends of sheets in center of pan.
3Spoon fruit mixture onto center of phyllo, forming 9-inch circle. Fold each sheet of phyllo up over filling, twisting and folding as necessary and leaving 3 1/2- to 4-inch opening in center. Brush phyllo with remaining butter.
4Bake 25 to 30 minutes or until phyllo is golden brown. Sprinkle with powdered sugar. Serve warm or cool with ice cream.
