Preheat air fryer to 375°F and lightly grease the basket with the avocado oil.
Pat the chicken sausages dry with a paper towel and insert a wooden skewer into each link.
In a shallow bowl, whisk together the yellow cornmeal, oat flour, baking powder, sea salt, black pepper, and garlic powder.
In a separate small bowl, whisk the egg and unsweetened almond milk together, then stir into the dry ingredients until a thick batter forms.
Pour the batter into a tall glass, dip each sausage to coat completely, and place immediately in the air fryer basket.
Air fry for 8-10 minutes, turning halfway through, until the exterior is golden and firm.
While the corn dogs cook, whisk the non-fat Greek yogurt, yellow mustard, and honey in a small bowl to create the dipping sauce.
