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 rest, covered, for 5 minutes. Fluff with a fork.
02 - In a large bowl, combine ground beef, egg, breadcrumbs, garlic, ginger, Sriracha, soy sauce, sesame oil, salt, pepper, and green onions. Mix gently until just combined to avoid tough meatballs.
03 - Shape mixture into 20 to 24 small meatballs, approximately 1 tablespoon each.
04 - Heat a nonstick skillet over medium heat. Add oil if necessary. Brown meatballs in batches, turning to brown all sides, about 6 to 8 minutes. Remove and set aside.
05 - Using the same skillet, sauté minced garlic for 30 seconds. Add Sriracha, soy sauce, honey, rice vinegar, ketchup, and sesame oil. Stir and bring to a simmer.
06 - Add cornstarch slurry and cook until sauce thickens, about 1 to 2 minutes.
07 - Return meatballs to skillet and toss to coat thoroughly. Simmer for 5 minutes to heat through.
08 - Plate meatballs over steamed rice and garnish with sliced green onions and sesame seeds.
