Slice the chicken breast into even strips and place them in a bowl with the buttermilk to marinate for 20 minutes.
In a shallow dish, whisk together the almond flour, garlic powder, onion powder, smoked paprika, sea salt, and black pepper.
Remove each chicken strip from the buttermilk, letting the excess drip off, and dredge thoroughly in the seasoned almond flour.
Lightly coat the air fryer basket with avocado oil spray and arrange the chicken strips in a single layer.
Air fry at 400°F for 10-12 minutes, flipping halfway through, until the coating is golden and the chicken is cooked through.
While the chicken finishes, toast the whole-grain protein waffle until it is crisp and warm.
Place the toasted waffle on a plate, top with the crispy chicken strips, and drizzle with the pure maple syrup before serving.
