Pulse the rolled oats in a blender until they reach a fine flour-like consistency.
Whisk the oat flour, egg white, Greek yogurt, and baking powder in a bowl to create a thick waffle batter.
Pour the batter into a preheated waffle iron and cook until golden brown and slightly crisp.
Slice the chicken breast into thin cutlets and soak them in buttermilk for 5 minutes.
Combine the almond flour, sea salt, black pepper, paprika, and garlic powder in a shallow dish.
Dredge the chicken pieces in the almond flour mixture, pressing firmly to ensure an even coating.
Heat the avocado oil in a non-stick skillet over medium heat and pan-sear the chicken for 4 minutes per side.
Place the crispy chicken atop the warm waffle and finish with a drizzle of pure maple syrup.
