Preheat the oven to 425 degrees and line a large baking sheet with parchment paper.
Roll out the pie dough and each roll cut into 6 rounds with a large cookie cutter.
Toss the apples, sugar, cinnamon, nutmeg and salt together in a medium bowl.
Add 1-2 tablespoons of the apple mixture into the center of half of the cut out pieces of pie dough. Place the remaining pieces of dough on top and use a fork to crimp the edges closed. Poke a few holes in the top of each.
Brush over each with the lightly beaten egg.
Bake for 15-18 minutes or until golden brown.
Remove from the oven and let cool.
Use food coloring to draw skulls, crossbones or other indicators of "poison" on top of the hand pies. Optionally, sprinkle sugar on top of the food coloring.
