Slice the chicken breast into even strips and pat dry with a paper towel.
In a small bowl, combine the almond flour, garlic powder, smoked paprika, sea salt, and black pepper.
Place half of the egg whites in a separate shallow dish. Dip each chicken strip into the egg whites, then dredge in the almond flour mixture until fully coated.
Place the coated chicken in an air fryer basket and lightly spray with a tiny bit of avocado oil. Air fry at 400°F for 10-12 minutes, flipping halfway through, until golden and crispy.
While the chicken cooks, prepare the waffle batter by whisking together the remaining egg whites, oat flour, cauliflower rice, and baking powder in a medium bowl.
Preheat a waffle iron and brush with the avocado oil. Pour the batter into the iron and cook until the waffle is firm and steam stops rising.
Serve the crispy chicken strips on top of the warm waffle and finish with a drizzle of maple syrup.
