01 - Preheat the oven to 430°F. Line a baking sheet with parchment paper.
02 - In a large bowl, combine ground meat, egg, breadcrumbs, garlic, scallions, soy sauce, ginger, salt, and pepper. Mix until just combined. Shape mixture into 16-20 small meatballs; arrange on the prepared baking sheet.
03 - Bake meatballs for 18-20 minutes, turning halfway, until browned and cooked through.
04 - Rinse rice under cold water until the water runs clear. Add rice and water to a saucepan. Bring to a boil, reduce heat to low, cover, and simmer for 12 minutes. Remove from heat and let stand, covered, for 5 minutes, then fluff with a fork.
05 - In a small bowl, whisk sriracha, mayonnaise, honey, soy sauce, rice vinegar, and sesame oil for the firecracker sauce until smooth. Set aside.
06 - Heat vegetable oil in a skillet over medium-high heat. Add carrot, bell pepper, and green beans; sauté for 4-5 minutes until just tender but still crisp. Season lightly with salt.
07 - When meatballs are done, toss them gently in about two-thirds of the firecracker sauce until evenly coated.
08 - Serve meatballs over jasmine rice with sautéed vegetables on the side. Drizzle with remaining sauce. Garnish with sesame seeds and extra scallions.
