Boil the chickpea pasta in salted water until al dente, then drain and finely chop the noodles into small pieces.
Sauté the ground turkey in a skillet over medium heat until fully browned and crumbled, then set aside to cool slightly.
In a large mixing bowl, combine the chopped pasta, cooked turkey, Greek yogurt, cheddar cheese, nutritional yeast, salt, pepper, and garlic powder.
Place the mixture in the refrigerator for 20 minutes to allow it to firm up, making it easier to shape.
Once chilled, scoop the mixture and roll into tight, even spheres roughly the size of a golf ball.
Whisk the egg white in a shallow bowl and place the panko breadcrumbs in a separate shallow dish.
Dip each ball into the egg white to coat, then roll thoroughly in the panko breadcrumbs until the surface is covered.
Lightly brush or spray the balls with avocado oil and place them in an air fryer basket.
Air-fry at 400°F for 10 to 12 minutes, shaking the basket halfway through, until the exterior is golden brown and crispy.
