Preheat your air fryer to 400°F and lightly grease your waffle iron with half of the avocado oil.
Slice the chicken breast into thin strips and toss in a bowl with almond flour, garlic powder, smoked paprika, sea salt, and black pepper until evenly coated.
Place the chicken in the air fryer basket and cook for 10-12 minutes, flipping halfway through, until the exterior is golden and the internal temperature reaches 165°F.
While the chicken cooks, place the rolled oats in a blender and pulse until they reach a fine flour consistency.
In a small bowl, whisk the oat flour with the egg whites and a pinch of salt until a smooth batter forms.
Pour the batter into the preheated waffle iron and cook for 4-5 minutes until the waffle is firm and crisp.
Plate the warm waffle, top with the crispy chicken strips, and finish with a drizzle of maple syrup.
