Preheat oven to 375F. Line a baking sheet with parchment paper and set aside.

Place chopped apples in a medium bowl, squeeze the juice of the lemon over apples and mix. Add the sugar and spices (cinnamon, nutmeg, all spice and ginger) and mix to incorporate. Set aside.

On a lightly floured surface, roll out the thawed puff pastry dough. Use a cookie cutter (2- 21/2 inch diameter), the top of a glass or metal ring from a mason jar to cut dough into circle pieces.Make sure you have an even number of circles so each pie has a top and bottom. Gather up excess dough, roll out and cut out additional circles if necessary.

Place half of the puff pastry circle on the prepared baking sheet. Add a scoop of apple mixture to each (approx. 1 Tbsp) leaving a border around the edges. Add caramel pieces (or caramel sauce). Top each pie with a puff pastry circle. and seal edges with fork. Using a fork also poke a few holes in the top of each pie.

Using a pastry brush, brush the top of each pie with egg. Place in the oven, cook 15-20 mins. until golden brown. Remove from oven and transfer to wire rack to cool.
