Apple-Blueberry Pie

Place sheet of foil on rack below middle oven rack to catch drips. Heat oven to 425 °F. Place pie crust in 9-inch glass pie pan as directed on box for One-Crust Filled Pie. In large bowl, mix filling ingredients; set aside. In medium bowl, mix topping ingredients with fork until crumbly. Spoon fruit into crust-lined pan. Spoon topping evenly over fruit. Place pie on middle oven rack over foil; bake 50 to 70 minutes or until apples are tender and edge is bubbly. After 20 minutes of baking, cover entire pie loosely with foil to prevent excessive browning. Cool 2 hours. Serve warm or cold.
