Preheat your air fryer to 400°F (200°C) for optimal crispiness.
Slice the chicken breast into even strips or bite-sized nuggets to ensure even cooking.
In a small shallow bowl, whisk the half egg until smooth to create an effective binder.
In a separate bowl, combine the arrowroot starch, almond flour, sea salt, black pepper, garlic powder, and smoked paprika.
Dip each chicken piece into the egg wash, then dredge thoroughly in the flour mixture until well coated.
Lightly spray the air fryer basket with avocado oil and arrange the chicken in a single layer without crowding.
Air fry for 10 to 12 minutes, flipping 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 crispy chicken atop the waffle and finish with a light drizzle of pure maple syrup before serving.
