Pigs in a blanket are juicy hot dogs or sausages wrapped up in flaky puff pastry or crescent dough. I prefer puff pastry but feel free to use crescent dough instead.
In a small bowl, beat the egg and water, then set it aside. Cut out 8 strips from the puff pastry sheet and then cut across 3 times so you have four rows.
Make sure to pinch the seams and brush the dough with the egg wash. Spray your air fryer basket with nonstick spray and place about 10-12 little smokies in the basket.
