Slice the chicken breast into even strips.
In a small bowl, whisk the Greek yogurt and lemon juice together to create a clean buttermilk alternative.
Submerge the chicken strips in the yogurt mixture and let them marinate for at least 10 minutes.
In a shallow dish, whisk together the almond flour, arrowroot powder, sea salt, black pepper, garlic powder, and paprika.
Remove each chicken strip from the yogurt, allowing the excess to drip off, and dredge thoroughly in the flour mixture until fully coated.
Lightly spray or brush the chicken with avocado oil and place in the air fryer basket.
Air-fry at 400°F for 10-12 minutes, flipping halfway through, until the exterior is golden-brown and the chicken is cooked to an internal temperature of 165°F.
While the chicken is finishing, toast the whole-grain waffle until it reaches your desired crispness.
Place the toasted waffle on a plate, top with the crispy chicken strips, and finish with a light drizzle of pure maple syrup.
