Preheat your air fryer to 400°F (200°C) to ensure a hot cooking environment for the chicken.
Slice the chicken breast into even strips and submerge them in a bowl with the buttermilk for 10 minutes to tenderize.
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, allowing the excess to drip off, then dredge thoroughly in the seasoned almond flour mixture.
Lightly coat the breaded chicken strips with avocado oil to help achieve a golden-brown finish.
Place the chicken in the air fryer basket in a single layer and cook for 12-15 minutes, flipping halfway through, until crispy and cooked through.
While the chicken finishes, toast the whole grain waffle until it reaches your desired level of crispness.
Place the hot chicken strips on top of the waffle and finish with a drizzle of pure maple syrup before serving.
