Preheat your air fryer to 400°F (200°C).
Slice the chicken breast into three long, even strips.
In a small bowl, whisk the nonfat Greek yogurt until smooth to use as a binder.
In a separate shallow dish, combine the almond flour, arrowroot starch, garlic powder, onion powder, smoked paprika, sea salt, and black pepper.
Dip each chicken strip into the yogurt, coating all sides, then dredge thoroughly in the almond flour mixture, pressing gently to adhere.
Lightly mist the air fryer basket with avocado oil, place the chicken inside, and spray the tops of the chicken strips with the remaining oil.
Air fry for 10-12 minutes, flipping halfway through, until the coating is golden and the chicken is cooked through.
While the chicken cooks, toast the whole grain waffle until crisp.
Place the toasted waffle on a plate, top with the crispy chicken strips, and finish with a drizzle of sugar-free maple syrup.
