Peel and slice apples into 8-10 pieces and set aside.
Roll out the pastry dough on a floured surface. Cut the pastry sheet into 9 equal pieces. Into the middle of each piece, place 4-5 pieces of apples, a spoonful of sugar and a teaspoon of flour into each one.
Fold the dough over the apples, forming little pockets from it. Place each pie on a lined baking sheet. Whisk the eggs in a separate bowl. Brush each pie with the whisked eggs, sprinkling them with some sugar.
Bake the pies at 415F for about 15 minutes or until golden brown.
