Boil the chickpea pasta shells in salted water until al dente, drain thoroughly, and finely chop into small pieces.
In a non-stick skillet over medium heat, cook the ground turkey until browned and fully cooked, breaking it into very fine crumbles with a spatula.
In a medium mixing bowl, combine the chopped pasta, cooked turkey, shredded sharp cheddar, Greek yogurt, garlic powder, onion powder, sea salt, and black pepper.
Mix the ingredients until a sticky dough forms, then divide and roll the mixture into 6 even, tightly packed balls.
Place the egg white in a small shallow bowl and the panko breadcrumbs in another.
Dip each ball into the egg white to coat, then roll gently in the panko breadcrumbs until a light, even layer is formed.
Preheat your air fryer to 375°F and lightly coat the basket with avocado oil.
Arrange the bites in the basket, leaving space between each, and lightly spray the tops with the remaining avocado oil.
Air fry for 8 to 10 minutes, shaking the basket halfway through, until the exterior is golden-brown and crispy.
