Preheat your air fryer to 400°F and lightly grease a waffle iron with a small amount of avocado oil.
Place the rolled oats in a high-speed blender and pulse until they reach a flour-like consistency.
In a small bowl, whisk together the oat flour, nonfat Greek yogurt, egg white, and baking powder until a smooth batter forms.
Pour the batter into the preheated waffle iron and cook for 4-6 minutes, or until the waffle is golden brown and firm.
While the waffle cooks, slice the chicken breast into even strips.
In a shallow dish, combine the almond flour, arrowroot starch, garlic powder, smoked paprika, sea salt, and black pepper.
Dredge each chicken strip in the almond flour mixture, pressing firmly to ensure the coating adheres.
Lightly mist the chicken strips with avocado oil and place them in the air fryer basket in a single layer.
Air fry the chicken at 400°F for 10-12 minutes, flipping halfway through, until the exterior is crispy and the internal temperature reaches 165°F.
Place the warm waffle on a plate, top with the crispy chicken strips, and finish with a drizzle of pure maple syrup.
