01 - Preheat oven to 400°F. Line a baking tray with parchment paper.
02 - In a large bowl, combine ground meat, egg, breadcrumbs, garlic, Sriracha, soy sauce, sesame oil, spring onions, salt, and pepper. Mix until just combined without overworking the mixture.
03 - With damp hands, shape the mixture into 20–24 small meatballs. Arrange evenly on the prepared baking tray.
04 - Bake for 18–20 minutes until golden brown and cooked through.
05 - While meatballs bake, combine Sriracha, honey, soy sauce, rice vinegar, sesame oil, and garlic in a small saucepan. Bring to a simmer over medium heat, stirring frequently until slightly thickened, approximately 3–4 minutes.
06 - Remove meatballs from oven and transfer to a large bowl. Pour glaze over meatballs and toss to coat evenly.
07 - Arrange glazed meatballs on a serving platter. Sprinkle with toasted sesame seeds and sliced spring onions before serving.
