Slice the chicken breast into three even strips or tenders.
In a small bowl, coat the chicken strips evenly with the plain Greek yogurt to act as a binder.
In a separate shallow dish, whisk together the arrowroot starch, almond flour, sea salt, black pepper, garlic powder, onion powder, and smoked paprika.
Dredge each yogurt-coated chicken strip into the flour mixture, pressing firmly so the coating adheres to all sides.
Lightly brush or spray the chicken strips with avocado oil.
Place the chicken in the air fryer basket at 400 degrees Fahrenheit and cook for 10-12 minutes, flipping halfway through, until the exterior is golden and the internal temperature reaches 165 degrees Fahrenheit.
While the chicken cooks, toast the whole-grain waffle until it is crisp and firm.
Place the toasted waffle on a plate, top with the crispy chicken tenders, and finish with a drizzle of pure maple syrup.
