Preheat your air fryer to 400°F (200°C).
Slice the chicken breast into three even strips or tenders.
In a small shallow bowl, whisk the egg whites until slightly frothy.
In a separate shallow bowl, combine the almond flour, arrowroot powder, garlic powder, onion powder, sea salt, and black pepper.
Dip each chicken strip into the egg whites, allowing excess to drip off, then dredge thoroughly in the almond flour mixture until well-coated.
Lightly grease the air fryer basket with avocado oil and place the chicken strips inside, ensuring they do not touch.
Air fry for 10-12 minutes, flipping halfway through, until the internal temperature reaches 165°F and the exterior is golden brown.
While the chicken is finishing, toast the whole-grain waffle until crisp.
Place the toasted waffle on a plate, top with the crispy chicken strips, and drizzle with the maple syrup before serving.
