Prepare the Meatballs: Start by placing your frozen meatballs in the bottom of the crockpot, spreading them out evenly to allow the glaze to coat every one of them.

Make the Sauce: In a mixing bowl, combine the hoisin sauce, soy sauce, honey, rice vinegar, garlic powder, and brown sugar. Whisk until all ingredients are fully blended and the mixture appears glossy.

Combine: Pour the luscious sauce over the meatballs in the crockpot, ensuring each meatball gets a generous coating for that irresistible flavor.

Cook: Cover the crockpot and set it to cook on high for 1-2 hours or on low for 2-4 hours. Stir once or twice during cooking to make sure the meatballs are evenly coated with the sauce.

Garnish: Once cooked, serve the meatballs warm, garnishing them with diced green onions and a sprinkle of sesame seeds to enhance their visual appeal and flavor.
