Preheat your air fryer to 375°F.
Pat the turkey sausages completely dry with a paper towel and insert a wooden skewer into the center of each link.
In a shallow dish or tall glass, whisk together the yellow cornmeal, almond flour, baking powder, sea salt, garlic powder, and onion powder.
In a separate small bowl, whisk the egg and unsweetened almond milk until the mixture is smooth.
Pour the wet ingredients into the dry cornmeal mixture and stir until a thick, cohesive batter forms.
Dip each skewered sausage into the batter, rotating it or using a spoon to ensure an even coating on all sides.
Lightly spray the air fryer basket with avocado oil to prevent sticking.
Place the coated sausages in the basket in a single layer, ensuring they do not touch each other.
Air fry for 10-12 minutes, gently turning them halfway through, until the cornmeal crust is firm and golden brown.
