Prepare the Fruit Filling: In a mixing bowl, combine the diced apples or peaches, granulated sugar, all-purpose flour, ground cinnamon, salt, and lemon juice (if making apple pies). Stir until the fruit is well coated. Set aside.
Roll Out the Pie Crust: On a lightly floured surface, roll out the pie crusts to about 1/8-inch thickness. Use a biscuit cutter or knife to cut out circles of dough, approximately 4-5 inches in diameter.
Fill the Dough Circles: Place a spoonful of the fruit filling onto one half of each dough circle, leaving a small border around the edges. Fold the other half of the dough over the filling to create a half-moon shape. Press the edges firmly to seal.
Crimp the Edges: Use a fork to crimp the edges of the pies to seal them further. This will also create a decorative pattern.
Heat the Oil: In a large skillet or frying pan, heat vegetable oil over medium heat until it reaches 350°F (175°C).
Fry the Pies: Carefully place the pies in the hot oil, a few at a time, making sure not to overcrowd the pan. Fry for 2-3 minutes on each side, or until golden brown and crispy.
Drain and Cool: Use a slotted spoon to transfer the fried pies to a paper towel-lined plate to drain excess oil. Allow them to cool slightly before serving.
Serve and Enjoy: Serve the fried apple or peach pies warm, either plain or dusted with powdered sugar. Enjoy the crispy exterior and the warm, gooey filling with every bite!
