Preheat your oven to 400°F (200°C).
In a large mixing bowl, combine the ground turkey, teriyaki sauce, tapioca flour, grated ginger, minced garlic, and chopped green onions. Mix until well combined.
Using your hands, scoop out a portion of the mixture and roll it into a ball about the size of a golf ball. Place on a baking sheet lined with parchment paper.
In a large skillet, heat a tablespoon of coconut oil over medium heat. Add the meatballs in batches, searing each for about 2-3 minutes on each side until golden brown.
Transfer the seared meatballs back to the baking sheet and bake for about 15-20 minutes, or until cooked through.
Drizzle with additional teriyaki sauce and serve hot, garnished with more chopped green onions if desired.
