Preheat your air fryer to 400°F and toast the whole grain waffle until it is crisp and warm.
Slice the chicken breast into even strips or bite-sized nuggets.
In a small shallow bowl, whisk the egg whites until they are slightly frothy.
In a second shallow dish, whisk together the almond flour, smoked paprika, garlic powder, sea salt, and black pepper.
Dip each piece of chicken into the egg whites, then dredge in the almond flour mixture, pressing firmly so the coating adheres.
Lightly coat the chicken pieces with the avocado oil and place them in the air fryer basket in a single layer.
Air fry for 10-12 minutes, flipping the chicken halfway through, until the coating is golden brown and the chicken is cooked through.
Place the crispy chicken pieces on top of the toasted waffle and finish with a drizzle of maple syrup.
