Slice the chicken breast into thick strips and place them in a bowl with the buttermilk to marinate for at least 15 minutes.
In a shallow dish, whisk together the almond flour, arrowroot starch, smoked paprika, garlic powder, sea salt, and black pepper.
Remove each chicken strip from the buttermilk, letting excess drip off, then dredge thoroughly in the flour mixture until well-coated.
Lightly coat the air fryer basket with avocado oil and arrange the chicken in a single layer, spraying the tops with the remaining oil.
Air fry at 400°F for 12-15 minutes, flipping halfway through, until the coating is golden brown and the chicken is cooked through.
While the chicken cooks, toss the shredded cabbage with apple cider vinegar and honey in a small bowl to create a crisp side slaw.
Serve the hot, crispy chicken immediately alongside the tangy cabbage slaw for a balanced, clean-eating feast.
