Preheat your air fryer to 400°F (200°C).
Slice the chicken breast into even strips and place them in a small bowl with the buttermilk to soak for 10 minutes.
In a shallow dish, whisk together the almond flour, arrowroot powder, smoked paprika, garlic powder, sea salt, and black pepper.
Remove each chicken strip from the buttermilk, letting excess drip off, then dredge in the flour mixture, pressing firmly to ensure an even coating.
Lightly brush or spray the chicken strips with avocado oil and place them in the air fryer basket in a single layer.
Air fry for 12-15 minutes, flipping halfway through, until the coating is golden-brown and the internal temperature reaches 165°F.
While the chicken is cooking, prepare the slaw by whisking the Greek yogurt, apple cider vinegar, honey, and mustard in a medium bowl.
Toss the shredded cabbage into the dressing until well-coated and serve immediately alongside the crispy chicken.
