Preheat oven to 400º F.
Meanwhile, heat 1 tbsp of avocado oil over medium heat in a pan, add diced onions and sauté until lightly golden.
If desired, when onions are lightly golden/caramelized, add spinach to the pan and sauté for a few minutes until spinach is wilted.
Place meat, egg, turmeric, coconut flour, garlic powder, chopped cilantro, salt and pepper in a mixing bowl.
Add the onion (and spinach) sauté mix to the rest of ingredients in the bowl and mix together.
Lightly oil hands, roll mixture into balls and transfer to a parchment paper-lined baking sheet.
Bake at 400º F for 20 minutes. Broil on high 5 minutes to brown tops.
Garnish with more cilantro or parsley and serve.
