Place a large baking sheet on the bottom rack of the oven, and preheat it to 425 degrees F.
Weigh out 430g (about ⅓) of the pie dough, placing the bigger half back in the fridge.
On a lightly floured surface, roll out the smaller piece into a circle about ⅛" in thickness and large enough to fit a 9" pie pan with some overhang.
Carefully transfer the dough to the pie dish and coax it up against the sides. Place in the fridge while the lattice pieces are made.
Roll out the remaining dough to about ⅛" in thickness and at least 12" in length on one side.
Cut out 12"x ½" strips and place on a small baking sheet. Chill the lattice strips in the fridge while the pie is assembled.
Take the pie dish out of the fridge and pour in the cherry pie filling, leaving behind most of the juices.
To make the lattice, arrange the vertical strips on the pie. With the vertical strips grouped into two, pull back every other "group" to the middle of the pie. Lay one strip down horizontally, then bring the grouped vertical strips back down. Repeat this until the entire lattice is complete.
Trim the excess pie dough to the very edge of the pie dish and squish together the edges so the bottom and the top dough adhere to each other. With the excess pie dough, you can make braids and line them along the edge of the pie, if desired.
Chill the assembled pie in the fridge for at least 15 minutes.
Brush an egg wash all over the pie, and sprinkle turbinado sugar on top.
Place the pie on top of the hot baking sheet and bake for about 45 minutes, or until the crust is deeply golden. Tent with foil towards the end if needed.
Allow the pie to cool for at least two hours or overnight. Serve with vanilla ice cream!
