Boil the chickpea pasta in salted water until al dente, then drain thoroughly.
In a medium bowl, combine the hot pasta with Greek yogurt, shredded cheddar, nutritional yeast, garlic powder, onion powder, salt, and pepper.
Stir the mixture vigorously until the cheese is melted and the pasta is coated in a thick, creamy sauce.
Place the mac and cheese in the refrigerator for at least 30 minutes to allow the mixture to firm up for rolling.
Once chilled, scoop the mixture and roll into 1-inch balls using your hands.
Whisk the egg whites in a small bowl and place the panko breadcrumbs in a separate shallow dish.
Dip each ball into the egg whites, then roll in the panko until evenly coated.
Arrange the balls in a single layer in an air fryer basket and lightly mist with avocado oil spray.
Air fry at 375°F for 8 to 10 minutes, shaking the basket halfway through, until the bites are golden brown and crispy.
