Preheat your air fryer to 400°F (200°C).
Slice the chicken breast into thick strips or nuggets.
In a small bowl, whisk the egg white until slightly frothy.
In a separate shallow dish, combine the almond flour, arrowroot powder, garlic powder, paprika, sea salt, and black pepper.
Dip each chicken piece into the egg white, then dredge in the almond flour mixture until evenly coated.
Lightly brush or spray the chicken with olive oil and place in the air fryer basket in a single layer.
Air fry for 10-12 minutes, flipping halfway through, until the coating is golden brown and the chicken is cooked through.
While the chicken cooks, toast the whole grain waffle until crisp.
Place the crispy chicken on top of the toasted waffle and drizzle with the sugar-free maple syrup before serving.
