Preheat oven to 450°F.Roll out dough to ¼-inch thick and, using a 5-inch biscuit cutter, cut round discs for pies.
Add 1 or 2 heaping tablespoons of the apple and pear mixture to one side of the disc, leaving the edges clear. Add some of the chopped chocolate covered cherries.
Lightly brush edges of circles with egg, fold in half and crimp edges with the tines of a fork.
Prick the center of each pie with a knife to form a vent for the heat to escape from.
Alternately, add the apple and pear mixture to the center of one disc, lightly brush the edge of the circle with egg wash and top with another disc and crimp edges with the tines of a fork.
Place pies on a baking sheet lined with parchment paper.
Brush with egg wash and sprinkles of decorative sugar. Bake for 15 minutes or until crust is golden.
Melt the chocolate truffles in a microwave for 15-second increments, stirring in between cooking times, until chocolate is melted.
