Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Pat the turkey franks completely dry with a paper towel and insert a wooden skewer into the end of each one.
In a medium mixing bowl, whisk together the cornmeal, oat flour, baking powder, sea salt, and garlic powder.
In a separate small bowl, whisk the egg, Greek yogurt, and honey until the mixture is smooth and well combined.
Pour the wet ingredients into the dry ingredients and stir until a thick, uniform batter forms.
Transfer the batter to a tall, narrow glass and dip each frank into the batter until fully coated, allowing any excess to drip off.
Place the coated franks on the prepared baking sheet, lightly spray with avocado oil, and bake for 15-18 minutes, turning halfway through, until the crust is firm and golden brown.
