Preheat your air fryer to 400°F and lightly coat the basket with the olive oil spray.
Slice the chicken breast into thin strips and place them in a small bowl with the buttermilk to soak for 10 minutes.
In a separate shallow dish, whisk together the almond flour, garlic powder, paprika, sea salt, and black pepper.
Remove each chicken strip from the buttermilk, letting any excess drip off, then dredge thoroughly in the almond flour mixture.
Arrange the chicken in a single layer in the air fryer basket and cook for 10 to 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 it reaches your desired level of crispness.
Place the toasted waffle on a plate, top with the hot crispy chicken strips, and finish with a drizzle of pure maple syrup.
