Preheat oven to 350 F. Grease baking sheet with coconut oil or line with parchment paper.
In large bowl, combine ground chicken, grated carrot and sweet potato, onion, garlic powder, Italian seasoning, egg, and flaxseed. The best way to combine all ingredients is to use your hands. Form into 1 1/2 inch diameter balls, place on baking sheet, and transfer to preheated oven.
Bake for approximately 20 to 24 minutes, until chicken has cooked through (meatballs must be 165 F when tested with a meat thermometer in the center). After 10 minutes, turn meatballs over so they cook evenly.
Meanwhile, in medium bowl, combine all sauce ingredients and whisk together. Set aside until meatballs are ready. Remove meatballs from oven and coat with sauce just before serving.
