Dump the pastry onto the lined baking sheet.
Spread pieces out as best you can with a small gap between each.

Notes
Store: In an airtight container at room temperature for 2-3 days. I don't recommend storing them in your fridge as they soften and turn soggy with the cold temperature.
Oven Reheating: Preheat oven to 350ºF (175ºC). Bake for 5-10 minutes or until warmed.
Air Fryer Reheating: Warm up at 350ºF (175ºC) for 5-10 minutes until heated. Keep an eye out that they don’t fly around the basket due to the air fryer fan.
