Slice the chicken breast into even strips to ensure uniform cooking.
In a small bowl, whisk the egg white until slightly frothy.
In a separate shallow dish, combine the almond flour, sea salt, black pepper, garlic powder, and smoked paprika.
Dip each chicken strip into the egg white, then dredge thoroughly in the almond flour mixture, pressing to adhere.
Lightly coat the air fryer basket with avocado oil and arrange the chicken in a single layer.
Air fry at 400°F (200°C) for 10-12 minutes, flipping halfway through, until the coating is golden and the chicken is cooked through.
While the chicken cooks, toast the whole grain waffle until crisp.
Place the crispy chicken strips over the warm waffle and drizzle with sugar-free maple syrup before serving.
