Preheat your air fryer to 400°F to ensure it is hot and ready for crisping.
Slice the chicken breast into even strips to ensure they cook at the same rate.
In a small shallow bowl, whisk the egg until the yolk and white are fully combined.
In a separate shallow bowl, combine the almond flour, garlic powder, onion powder, sea salt, and black pepper.
Dip each chicken strip into the egg wash, then dredge thoroughly in the almond flour mixture until fully coated.
Lightly coat the chicken strips with avocado oil and place them in the air fryer basket in a single layer.
Air fry the chicken for 12-15 minutes, flipping halfway through, until the coating is golden and the chicken is cooked through.
Toast the grain-free waffle in a toaster or oven until it is firm and crisp.
Place the hot chicken strips on top of the toasted waffle and finish with a drizzle of pure maple syrup.
