Preheat oven to 350° F. In large bowl, combine all meatball ingredients except oil. The key to good meatballs is not to over mix them. Just gently combine the ingredients until everything is evenly distributed. Form the mixture into golf-ball sized meatballs.
Heat oil in large skillet over medium-high heat. In batches (don't crowd the pan!), brown the meatballs on all sides. Transfer meatballs to rimmed baking pan and transfer to oven. Bake 10 minutes or until internal temperature reaches 160° F.
Meanwhile, in small saucepot, combine all glaze ingredients. Cook over medium heat 5 minutes or until mixture is slightly thickened.
To serve, brush meatballs with glaze and sprinkle with green onion and sesame seeds.
