Preheat oven to 350 degrees. Cover a large baking sheet with foil, spray with cooking spray, and set aside.
In a large bowl, combine the ground turkey, onion, garlic, ginger, parsley, five-spice powder, egg, breadcrumbs, salt and pepper and mix with your hands until just combined.
Use a medium cookie scoop, or tablespoon, to form evenly sized meatballs, and roll between the palms of your hands to make them smooth. Place the meatballs on the prepared baking sheet, at least an inch apart.
Bake until the meatballs are firm to the touch and cooked through, about 15 minutes.
Meanwhile, combine all of the sauce ingredients in a small pan, over medium heat. Whisk to combine and bring to a simmer, for 8-10 minutes, until sauce has slightly thickened. Keep warm.
Once the meatballs are done cooking, remove from oven and brush the tops with sauce. Return the pan to the oven for an additional 5 minutes.
Toss the meatballs with the remaining sauce and serve immediately. Either with toothpicks as appetizers, or over rice with your favorite veggie for a meal!
