Preheat your air fryer to 400°F and lightly spray the basket with a small amount of avocado oil.
Slice the chicken breast into even strips and pat them dry with a paper towel to ensure the coating sticks.
In a shallow bowl, whisk together the almond flour, arrowroot starch, garlic powder, onion powder, sea salt, and black pepper.
Lightly brush the chicken strips with avocado oil, then dredge each piece in the almond flour mixture until fully and evenly coated.
Place the chicken in the air fryer basket in a single layer and cook for 10-12 minutes, flipping halfway through, until golden and crispy.
While the chicken cooks, toast the whole-grain waffle in a toaster or oven until it reaches your desired level of crispness.
Place the toasted waffle on a plate, top with the crispy chicken strips, and drizzle with the pure maple syrup before serving immediately.
