Remove the pastry from the refrigerator about 30 minuets before you need to use it. This will make it easier to handle.
Preheat oven to 375F and line baking sheet with parchment. Roll out pie dough on parchment lined baking sheet. Place Apple Pie filling in the middle of the crust leaving about a 2"-3" border,
Fold dough over and pinch to enclose peaches, leaving the center open. Sprinkle struesel mixture over the top of the exposed apple pie filling. Bake for 35-40mins, until crust is golden and struesel is lightly browned. Cool on sheet for 10mins. Slide off with parchment onto wire rack to cool completely. Store in fridge. Serve cold or reheated.
