Preheat your oven to 350°F (175°C) and prepare a baking sheet with parchment paper or non-stick spray.

Roll out the thawed pie crust on a floured surface to about 1/8 inch thick and cut out 2.5-inch circles.

Place one Hershey Kiss at the center of each dough circle and fold the dough over to form a half-moon shape, sealing the edges.

Whisk the egg white with 1 Tbsp of water and brush this mixture over each cookie.

Sprinkle granulated sugar or sea salt on each cookie and bake for 15-20 minutes until golden brown.

Allow cooling on the baking sheet for 5 minutes, then drizzle with caramel topping and sprinkle with sea salt before serving.
