Preheat your air fryer to 375°F to ensure the coating sears quickly for maximum crunch.
In a medium mixing bowl, whisk together the egg and nonfat Greek yogurt until the mixture is completely smooth.
Stir in the yellow cornmeal, almond flour, baking powder, sea salt, and garlic powder until a thick, uniform batter forms.
Pat the turkey sausages dry with a paper towel and insert a wooden skewer into the end of each sausage.
Dip and roll each sausage into the batter until fully and thickly coated, using a spoon to help spread it evenly.
Lightly grease the air fryer basket with avocado oil and arrange the sausages in a single layer, ensuring they do not touch.
Air fry for 10-12 minutes, rotating the sausages halfway through, until the exterior is golden brown and firm.
While the corn dogs cook, whisk the yellow mustard and honey together in a small ramekin to serve as a dipping sauce.
