Preheat your air fryer to 400°F (200°C) to ensure a hot cooking environment for the chicken.
Slice the chicken breast into three even strips to ensure they cook at the same rate.
In a small shallow bowl, whisk the egg white until it becomes slightly frothy.
In a separate shallow dish, whisk together the almond flour, garlic powder, smoked paprika, sea salt, and black pepper.
Dip each chicken strip into the egg white, allowing the excess to drip off, then dredge thoroughly in the almond flour mixture.
Lightly grease the air fryer basket with the avocado oil and place the chicken strips inside in a single layer.
Air fry for 10-12 minutes, flipping the strips halfway through, until the coating is golden brown and the internal temperature reaches 165°F.
While the chicken is finishing, toast the whole grain waffle in a toaster or oven until warm and slightly firm.
Place the toasted waffle on a plate, top with the crispy chicken strips, and finish with a drizzle of maple syrup.
