Third Step: Add cold water incrementally and mix until a dough forms; wrap in plastic and chill for at least 30 minutes.

Fourth Step: Prepare the peach filling by tossing sliced peaches with sugar, cornstarch, and vanilla extract; set aside.

Fifth Step: Roll out the chilled dough on a floured surface into a rough circle about 12 inches wide.

Sixth Step: Transfer the dough to the baking sheet and arrange the peach mixture in the center, leaving a 2-inch border.

Seventh Step: Fold the edges of the dough over the peaches, pleating as needed to enclose the filling partially.

Eighth Step: Brush the crust with a plant-based milk for vegan option or regular milk for traditional recipes; sprinkle with sugar if desired.

Ninth Step: Bake for 40-45 minutes or until the crust is golden and peaches are tender.

Final Step: Remove from oven, let cool slightly, then serve warm or at room temperature. Adjust timing and ingredients for dietary preferences as needed.
