Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
In a large bowl, combine the ground beef (or mix), breadcrumbs, chopped green onions, minced garlic, grated ginger, egg, sesame oil, salt, and pepper. Mix until all ingredients are well incorporated.
Using your hands, shape the mixture into meatballs, about 1 inch in diameter, and place them on the prepared baking sheet, spaced apart.
Bake the meatballs in the preheated oven for 15-20 minutes, or until they are cooked through and slightly browned.
While the meatballs are baking, whisk together the gochujang, honey, soy sauce, and rice vinegar in a small saucepan over medium heat. Bring the mixture to a gentle simmer and cook for about 5 minutes until slightly thickened. Remove from heat.
When the meatballs are done baking, remove them from the oven and transfer them to a large bowl. Pour the BBQ glaze over the meatballs and gently toss until they are well coated.
Return the coated meatballs to the baking sheet. Bake again for an additional 5 minutes to allow the glaze to become sticky and shiny.
Garnish with sesame seeds and extra chopped green onions. Serve the sticky meatballs with steamed rice or lettuce wraps for a delightful meal!
