Step 1

Preheat oven to 400 F.

Step 2

In a large mixing bowl, combine beef with bread crumbs, onion, green onions, egg, soy sauce, brown sugar, garlic powder, salt and pepper.  Mix well to form into a uniform consistency.

Step 3

Take 2 spoonfuls of beef mixture at a time and roll into 1.5-inch thick meatballs. Transfer the meatballs into a large half sheet baking pan lined with parchment paper and lightly coat with some oil to keep them from sticking, if needed.

Step 4

Bake for 15 minutes until fully cooked, and set aside. The internal temperature should reach 160F, as read on a meat thermometer.

Step 5

In a medium mixing bowl, add vinegar, brown sugar, soy sauce, honey, garlic, cornstarch and water. Whisk well to combine until cornstarch and sugar dissolves.

Step 6

In a shallow saucepan, stir in sauce mixture and heat over medium heat for 3-4 minutes. Keep stirring until thickened to a desired consistency.

Step 7

Add the meatballs to the saucepan and toss well to coat evenly. Sprinkle with green onions and sesame seeds and serve warm on its own or over a bowl of steamed rice or fried rice.
