Preheat oven to 400°F; line a cookie sheet with parchment paper or foil and grease lightly.
Slice dough into strips about 1/2 inch wide and 2 inches long.
Arrange strips onto the cookie sheet and sprinkle with cinnamon and sugar.
Bake for 15 minutes.
Prepare the peach pie filling. In a large saucepan, stir together the water, lemon juice, sugar, and cornstarch. Cook over medium heat until thickened and bubbly, roughly 5 minutes. Once it bubbles, cook for another 2-3 minutes, constantly stirring.
Remove from heat and stir in vanilla extract, then the peaches. Cool to room temperature and enjoy!
