01 - Rinse rice under cold water until clear. Combine rice, water, and salt in a saucepan and bring to a boil. Reduce heat to low, cover, and simmer for 15 minutes. Remove from heat and let stand covered for 5 minutes. Fluff with a fork.
02 - In a large bowl, combine ground beef, egg, breadcrumbs, garlic, ginger, 2 tablespoons Sriracha, soy sauce, sesame oil, salt, pepper, and green onions. Mix gently until just incorporated. Shape into 20–24 small meatballs, about 1 tablespoon each.
03 - Heat a large nonstick skillet over medium heat. Add a splash of oil if needed. Cook meatballs in batches, turning to brown all sides for 6–8 minutes. Remove and set aside.
04 - In the same skillet, sauté garlic for 30 seconds. Add remaining Sriracha, soy sauce, honey, rice vinegar, ketchup, and sesame oil. Stir and bring to a simmer.
05 - Stir in cornstarch slurry and cook for 1–2 minutes until sauce thickens slightly.
06 - Return meatballs to skillet, toss to coat with sauce, and simmer for 5 minutes until heated through.
07 - Place meatballs over steamed rice and garnish with sliced green onions and sesame seeds.
