Wash and dry the cherries, then remove the pit.
In a large bowl combine the fresh pitted cherries, the cherry pie filling, cinnamon, nutmeg, and orange juice then transfer the mixture to a deep dish pie plate. Note- if the cherries are large I sometimes cut them in half.
Cover the cherries with the pie dough, trim any excess dough to 1" inch of the pie plate. Tuck the dough inside the rim of the pie plate and crimp the edge like you would on a pie.
Sprinkle sugar on top of the pie dough.
Place the pie plate on a baking sheet to catch any drips and put it in the oven and bake for 30 minutes.
Remove the baking sheet from the oven and using a knife, cut the pie crust into 1" squares, then with a spoon gently poke down the edges of the squares into the hot filling. You do not have to do all the squares.
Return to the oven and bake for 25 minutes until the crust is golden brown and the filling is bubbly. Check on the pandowdy to make sure the crust is not getting too brown.
Remove from the oven and let the pandowdy cool for about 20 minutes before serving. Cover any leftovers with foil or plastic wrap for several days.
