01 - Preheat the oven to 400°F and line a baking sheet with parchment paper.
02 - In a large bowl, combine ground beef, garlic, onion, egg, breadcrumbs, Sriracha, soy sauce, sesame oil, salt, black pepper, and cilantro. Mix gently until just combined to avoid overworking.
03 - Form the mixture into 20 to 24 small meatballs, approximately one tablespoon each, and arrange them evenly on the prepared baking sheet.
04 - Bake in the preheated oven for 18 to 20 minutes until the meatballs are browned and cooked through.
05 - Rinse rice under cold water until clear. Bring water and salt to a boil in a saucepan. Add rice, reduce heat to low, cover, and simmer for 12 to 15 minutes until tender and liquid absorbed. Fluff with a fork.
06 - Whisk together Sriracha, honey, soy sauce, rice vinegar, and sesame oil in a small saucepan. Simmer over medium-low heat for 2 to 3 minutes until slightly thickened.
07 - Once cooked, toss the meatballs gently in the prepared Sriracha sauce until evenly coated.
08 - Serve the sauced meatballs over the cooked rice. Garnish with sliced spring onions, sesame seeds, and fresh cilantro if desired.
