Preparation: Start by laying out your pie crusts on a flat surface, using a rolling pin to flatten if needed.

Cutting the Dough: Using a round cookie cutter or the rim of a glass, cut out circles from your dough.

Filling: Spoon about 1 to 2 tablespoons of the blueberry pie filling into the center of half of the circles, ensuring you leave space around the edges.

Sealing: Take the remaining circles and place them on top of the filled ones. Press down the edges gently with your fingers, then use a fork to crimp them shut. This not only seals the pies but also gives a decorative edge.

Egg Wash: In a small bowl, beat the egg with a tablespoon of water. Brush this mixture over the top of each hand pie. If desired, sprinkle with sugar for a sweet crust.

Air Frying: Preheat your air fryer to 375°F (190°C). Once heated, place the hand pies in a single layer, ensuring they don't touch. Cook for 8-10 minutes or until they're golden brown, turning halfway through.

Serving: Once cooked, remove the hand pies from the air fryer and allow them to cool on a wire rack for a few minutes before serving.
