Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper. This will help the meatballs cook evenly and prevent sticking.
In a large mixing bowl, combine the ground turkey, egg, diced green onion, sea salt, coconut flour, avocado oil, minced ginger, minced garlic, 1 cup of the freshly squeezed orange juice, orange zest, coconut aminos, rice vinegar, crushed red pepper flakes, salt, pepper, and tapioca starch. Mix well until all ingredients are combined.
Using your hands, scoop out a portion of the mixture and roll it into a ball, about 1 to 1.5 inches in diameter. Place the meatballs on the prepared baking sheet, ensuring they're evenly spaced.
Bake the meatballs in the preheated oven for 25-30 minutes, or until they reach an internal temperature of 165°F (74°C) and are golden brown on the outside.
While the meatballs are baking, prepare the orange sauce. In a small saucepan, combine the remaining 1/2 cup of orange juice, coconut aminos, rice vinegar, and a pinch of crushed red pepper flakes. Bring to a gentle simmer over medium heat and let it reduce for about 5-7 minutes, or until slightly thickened.
Once the meatballs are cooked, remove them from the oven and drizzle the orange sauce over them. Toss gently to coat.
Serve the meatballs over cauliflower rice or your choice of cooked rice. Garnish with orange segments, additional diced green onions, and a sprinkle of sesame seeds for a delightful crunch.
