Preheat your oven to 400°F (200°C). While it's heating, line a baking sheet with parchment paper to prevent sticking.
In a large mixing bowl, add the ground beef (or chicken). Incorporate the breadcrumbs, chopped green onions, grated Parmesan, the large egg, minced garlic, grated ginger, salt, and black pepper. Use your hands or a spatula to thoroughly mix all the ingredients until they are evenly blended.
With your hands, form the mixture into small meatballs, approximately 1 inch in diameter. Arrange the meatballs on the prepared baking sheet, spacing them evenly.
Place the baking sheet in the preheated oven and bake the meatballs for 20-25 minutes. They should be cooked through and browned nicely on the exterior.
While the meatballs are baking, it's time to make the glaze. In a medium-sized saucepan over medium heat, combine the sweet chili sauce, soy sauce, sesame oil, and rice vinegar. Stir the ingredients well and bring the mixture to a gentle simmer. Once it starts simmering, remove the saucepan from the heat.
When the meatballs are done baking, transfer them to a large bowl. Immediately pour the sweet chili glaze over the hot meatballs. Gently toss them in the glaze until they are completely coated and glistening.
Serve the glazed meatballs warm on a platter or individual plates, showered with sesame seeds and garnished with fresh cilantro for an added touch of flavor and color.
