Preheat your air fryer to 400°F (200°C) to ensure a quick and even crisp.
Cut the chicken breast into small, even bite-sized pieces for uniform cooking.
In a small bowl, whisk the egg white until it becomes slightly frothy.
In a separate shallow dish, combine the almond flour, garlic powder, onion powder, sea salt, black pepper, and smoked paprika.
Dip each chicken piece into the egg white, then roll in the almond mixture until thoroughly and evenly coated.
Place the chicken bites in the air fryer basket in a single layer and cook for 8-10 minutes until they are golden brown and cooked through.
In a small ramekin, stir together the Greek yogurt and lemon juice to create a bright and tangy dipping sauce to serve on the side.
