Preheat your oven to 400°F (200°C).

In a mixing bowl, combine the diced apples, granulated sugar, ground cinnamon, lemon juice, and flour.

On a lightly floured surface, roll out the pie crust to about 1/8 inch thick.

Use a cookie cutter or a glass to cut out circles from the rolled dough, about 3 inches in diameter.

Place a tablespoon of the apple filling in the center of each circle.

Fold the dough over the filling and pinch the edges to seal.

Place the filled bites on a baking sheet lined with parchment paper.

Brush the tops with an egg wash for a shiny finish, if desired.

Bake in the preheated oven for 20 to 25 minutes, or until golden brown.

Allow the bites to cool slightly before serving.
