Slice the chicken breast into even strips and place them in a small bowl with the buttermilk to marinate for at least 15 minutes.
In a separate shallow dish, whisk together the almond flour, arrowroot powder, garlic powder, onion powder, smoked paprika, sea salt, and black pepper.
Remove each chicken strip from the buttermilk, allowing excess to drip off, then dredge thoroughly in the flour mixture, pressing down to ensure a thick coating.
Place the coated chicken in the air fryer basket and lightly spray with avocado oil.
Air-fry at 400°F for 12-15 minutes, flipping halfway through, until the coating is golden brown and the chicken is cooked through.
While the chicken finishes, toast the whole wheat waffle until it reaches your desired level of crispness.
Place the toasted waffle on a plate, top with the crispy chicken strips, and finish with a drizzle of pure maple syrup.
