Place the chicken breast in a shallow bowl and cover with buttermilk, marinating for at least 30 minutes in the refrigerator.
In a small bowl, whisk together the almond flour, arrowroot powder, garlic powder, onion powder, sea salt, and black pepper.
Remove the chicken from the buttermilk, letting excess drip off, and dredge thoroughly in the flour mixture until well-coated.
Preheat your air fryer to 375°F and lightly coat the basket with avocado oil spray.
Place the chicken in the basket, spray the top of the chicken with avocado oil, and air fry for 12-15 minutes, flipping halfway through, until the internal temperature reaches 165°F.
While the chicken cooks, whisk together the Greek yogurt, apple cider vinegar, and honey in a medium bowl.
Toss the shredded cabbage mix into the yogurt dressing until evenly coated.
Serve the crispy chicken immediately alongside the chilled creamy slaw.
