Slice the chicken breast into thick strips and place them in a bowl with the low-fat buttermilk to soak for at least 15 minutes.
In a shallow dish, combine the almond flour, garlic powder, onion powder, paprika, sea salt, and black pepper, mixing well to distribute the spices.
Remove each chicken strip from the buttermilk, allowing the excess to drip off, then dredge thoroughly in the almond flour mixture, pressing the coating onto the meat.
Lightly brush or spray the chicken strips with olive oil and place them in an air fryer basket at 400°F for 12 to 15 minutes, flipping halfway through until the exterior is golden and crunchy.
While the chicken cooks, toss the shredded cabbage with apple cider vinegar and a pinch of salt to create a bright, acidic slaw.
Serve the crispy chicken immediately alongside the fresh cabbage slaw for a balanced, clean-eating feast.
