In a large bowl, combine the pork, turkey or beef, green onions, garlic, sesame oil, fish sauce, and vinegar.
Mix well with your hands, and form into 36 1½-inch meatballs.
In a large skillet, heat the coconut oil over medium heat.
Add the meatballs to the skillet, and cook, turning occasionally, to brown them on all sides.
Place the browned meatballs in a slow cooker.
In a small bowl, combine the coconut milk, chicken broth, curry paste, and maple syrup.
Pour over the meatballs.
Cook the meatballs on low for 5-6 hours or on high for 4-5 hours.
Add the lime juice, and stir gently.
In a small bowl, stir together the arrowroot starch and cold water.
Add the mixture to the slow cooker, and stir gently.
Cook, uncovered, on high for 15 minutes, and serve.
