01 - Preheat oven to 400°F. Line a baking sheet with parchment paper.
02 - In a large bowl, combine ground beef, garlic, onion, egg, breadcrumbs, sriracha sauce, soy sauce, sesame oil, salt, pepper, and cilantro. Mix until just combined without overmixing.
03 - Shape mixture into 20-24 small meatballs, approximately 1 tablespoon each. Place on prepared baking sheet.
04 - Bake for 18-20 minutes until meatballs are browned and cooked through.
05 - Rinse rice under cold water until water runs clear. In a saucepan, bring 2 cups water and 1/2 tsp salt to a boil. Add rice, reduce heat to low, cover, and simmer for 12-15 minutes until tender and water is absorbed. Fluff with a fork.
06 - In a small saucepan, whisk together sriracha sauce, honey, soy sauce, rice vinegar, and sesame oil. Bring to a simmer over medium-low heat and cook for 2-3 minutes until slightly thickened.
07 - Once meatballs are cooked, toss them in the sriracha sauce until well coated.
08 - Serve meatballs over cooked rice. Garnish with sliced spring onions, sesame seeds, and fresh cilantro.
