For a healthy and delicious snack, try making apple chips in the Ninja Foodi air fryer. Slice apples thinly and toss them with a little cinnamon and sugar. Place the apple slices in a single layer in the air fryer basket and cook for about 10-15 minutes, until they are crispy and golden. The result is a sweet and crunchy snack that is perfect for satisfying your cravings.
