Slice the chicken breast into even strips and place them in a small bowl with the buttermilk to marinate for 15 minutes.
In a separate 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, then dredge thoroughly in the almond flour mixture, pressing to ensure a thick coating.
Lightly mist the coated chicken strips with avocado oil and place them in an air fryer basket at 400°F.
Cook the chicken for 10-12 minutes, flipping halfway through, until the exterior is golden-brown and the internal temperature reaches 165°F.
While the chicken finishes, toast the whole-grain protein waffle until it is warm and slightly crisp.
Place the hot waffle on a plate, top with the crispy chicken strips, and finish with a drizzle of maple syrup.
