Line a baking sheet with parchment. Roll out your pie dough to about 1/8th inch thickness. Cut seven 4 inch circles from the dough. You may need to gather your scraps and re-roll to get all seven cut outs, just be careful not to overwork the dough! Place the circles on the prepared baking sheet and brush the outer half inch edge of all the circles with the egg and water mixture. Spoon about 1 tablespoon of the pear filling into the center of each circle. Fold each in half and crimp the edges together with a fork. Place the sheet pan in the freezer for 30 minutes to chill the pies well.
Preheat the oven to 375 degrees Fahrenheit while you wait for your pies to chill.
