For the meatballs, mix the ground beef, ground pork, egg, bread crumbs, milk, salt and pepper together. Knead the mixture with your hands until thoroughly combined. Roll into 1 1/2 inch meatballs and place on a baking sheet lined with parchment paper. Bake in the oven at 350 for about 20 minutes.
Place remaining ingredients in a saucepan and simmer for 5-10 minutes to create a sauce.
After taking the meatballs out of the oven, toss them in the sauce.
Serve immediately with rice and sliced green onions
If desired, you can throw the meatballs tossed in the sauce in a slow cooker. Keep it on low until ready to eat. Great party food!
