Slice the chicken breast into even strips or medallions.
Place the chicken in a bowl with the buttermilk and let it soak for 10 minutes to tenderize.
In a shallow dish, whisk together the panko breadcrumbs, smoked paprika, garlic powder, onion powder, sea salt, and black pepper.
Remove each piece of chicken from the buttermilk, letting the excess drip off, then dredge thoroughly in the seasoned panko mixture.
Lightly coat your air fryer basket with the avocado oil and arrange the chicken in a single layer.
Air fry at 400°F for 10-12 minutes, flipping halfway through, until the coating is golden brown and the chicken is cooked through.
While the chicken is cooking, whisk together the apple cider vinegar and Dijon mustard in a medium bowl.
Toss the shredded cabbage into the dressing until evenly coated to create a fresh, tangy slaw.
Serve the crispy chicken immediately alongside the slaw for a balanced and crunchy feast.
