If not already, defrost the pastries per the box instructions and unroll.
Cut the pastries with a pizza cutter into 6 rectangles per sheet, so 12 total.
In a medium size bowl, combine the ground sausage, parsley, and garlic.
Carefully stretch the pastry dough just a bit, then fill the center with the sausage mixture just enough to fill it similar size to a small round sausage.
Then fold over the pastry dough to fully cover the sausage.
Place this in a greased air fryer basket, use grapeseed oil spray to grease it or use parchment paper.
Once they are in the basket, carefully combine the egg and water to make an egg wash.
Use a brush and brush on each pastry.
Sprinkle with additional dried parsley.
Cook in the air fryer at 390*F for 8-10 minutes, and turn them at the halfway mark.
In order to be fully done the sausage needs to be at least 165*F internal temperature.
Carefully remove and serve or save for later and reheat. Continue for remaining batches.
