01 - Preheat the oven to 400°F. Line a baking sheet with parchment paper.
02 - In a large bowl, combine ground beef, egg, breadcrumbs, garlic, ginger, Sriracha, soy sauce, sesame oil, spring onions, salt, and pepper. Mix gently until just combined without overworking.
03 - Shape the mixture into 20 evenly sized meatballs and arrange them on the prepared baking sheet.
04 - Place meatballs in the oven and bake for 15 to 18 minutes, or until cooked through and browned.
05 - While baking, whisk together Sriracha, honey, soy sauce, rice vinegar, and sesame oil in a small saucepan over medium heat. Simmer for 2 to 3 minutes, stirring occasionally until slightly thickened.
06 - Transfer meatballs to a large bowl and pour the warm glaze over them. Toss gently to coat evenly.
07 - Serve hot, optionally garnished with sesame seeds and sliced spring onions.
