My new favorite air fryer recipe is mini Nutella turnovers.
Preheat air fryer to 400°
Divide store bought puff pastry sheet into 12 squares.
Put a spoonful of Nutella in the center of each square
Egg wash the edges and fold each square in half diagonally, turnover-style.
Egg wash the top of each turnover
Cook in air fryer for 6 minutes (you can only fit about four in the basket at a time, so you’ll have to cook them in batches)
Dust with powdered sugar (it hides any filling leakage or wonky folding 
)
(PS - They’re also great next day with a cup of tea or coffee for breakfast 
)
