Roll into 1-1/2 inch balls and place onto a cookie sheet (it should make about 20 balls.) Bake until no longer pink inside, about 16-18 minutes. Make sure you don't over-bake, so the meat doesn't get tough.
While the meatballs cook, stir togehter ALL of the sauce ingredients in a medium pot and bring to a boil on high heat. Once boiling, cook for 1.5 minutes, stirring frequently.
Once the sauce has boiled for 1.5 minutes, turn the heat down to medium and simmer until the sauce begins to thicken and reduce, about 8-9 minutes, stirring frequently
Once reduced, pour the sauce into a high powered blender, or a small 3 cup food processor, and blend until smooth. Transfer to a large bowl and cover to keep warm.
Once the meatballs are done, add them into the sauce and stir until well coated.
Serve over side of choice, garnish with extra green onion and DEVOUR
