In a small bowl, whisk together the unsweetened almond milk and lemon juice to create a dairy-free buttermilk substitute.
Place the chicken breast in the mixture and let it marinate for at least 15 minutes to tenderize.
In a separate shallow dish, whisk together the almond flour, smoked paprika, garlic powder, sea salt, and black pepper.
Remove the chicken from the marinade, letting the excess liquid drip off, then dredge it thoroughly in the seasoned almond flour mixture.
Lightly coat the breaded chicken with avocado oil and place it in the air fryer basket.
Air fry at 375°F for 12-15 minutes, flipping halfway through, until the exterior is golden-brown and the internal temperature reaches 165°F.
While the chicken is finishing, toast the whole grain waffle until it is warm and slightly firm.
Place the crispy chicken on top of the toasted waffle and finish with a drizzle of sugar-free maple syrup.
