Slice the chicken breast into even strips and soak them in the low-fat buttermilk for 10 minutes to tenderize.
In a shallow bowl, whisk together the arrowroot powder, almond flour, garlic powder, onion powder, paprika, sea salt, and black pepper.
Dredge each chicken strip through the flour mixture, pressing firmly to ensure the coating adheres to all sides.
Place the coated chicken strips in the air fryer basket in a single layer and spray lightly with avocado oil.
Air fry at 400°F for 12-15 minutes, flipping the strips halfway through, until the coating is golden and the chicken is cooked through.
Toast the whole grain waffle until it is warm and slightly firm to the touch.
Place the toasted waffle on a plate, top with the crispy chicken strips, and finish with a drizzle of pure maple syrup.
