01 - Set the oven to 400°F and line a baking sheet with parchment paper.
02 - In a large bowl, combine ground meat, breadcrumbs, egg, garlic, finely chopped green onions, Sriracha sauce, soy sauce, salt, and black pepper. Mix gently until just combined to avoid tough meatballs.
03 - Form the mixture into 1-inch diameter balls and arrange them evenly on the prepared baking sheet.
04 - Bake in the preheated oven for 18–20 minutes until browned and cooked through.
05 - Meanwhile, whisk together Sriracha, honey, soy sauce, rice vinegar, and sesame oil in a small saucepan over medium heat. Simmer for 2–3 minutes, stirring occasionally, until the glaze slightly thickens.
06 - Transfer the baked meatballs to a large bowl. Pour the warm glaze over them and toss gently to ensure each meatball is evenly coated.
07 - Arrange the glazed meatballs on a serving plate. Sprinkle with sesame seeds and sliced green onions before serving.
