Slice the chicken breast into three even strips.
In a small shallow bowl, whisk the egg until smooth.
In a separate shallow bowl, combine the almond flour, arrowroot powder, 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 spray or brush the chicken with avocado oil and place in the air fryer basket.
Air fry at 400°F for 10-12 minutes, flipping halfway through, until the internal temperature reaches 165°F and the coating is golden brown.
While the chicken cooks, toast the whole grain waffle until crisp.
Place the baby spinach on a plate as a fresh base, top with the toasted waffle, and place the crispy chicken strips on top.
Finish by drizzling the sugar-free maple syrup over the chicken and waffle.
