01 - Combine ground meat, egg, breadcrumbs, minced garlic, scallions, soy sauce, grated ginger, salt, and pepper in a large mixing bowl. Mix gently until ingredients are just incorporated.
02 - Line a baking sheet with parchment paper. Form mixture into 16 to 20 uniform meatballs and arrange evenly on the baking sheet. Bake at 430°F for 18 to 20 minutes, turning halfway, until browned and cooked through.
03 - Rinse rice under cold water until the water runs clear. Combine rice and water in a saucepan, bring to a boil, then reduce heat to low. Cover and simmer for 12 minutes. Remove from heat, keep covered for 5 minutes, then fluff with a fork.
04 - In a small bowl, whisk together sriracha, mayonnaise, honey, soy sauce, rice vinegar, and sesame oil until the sauce is homogeneous and smooth. Set aside.
05 - Heat vegetable oil in a large skillet over medium-high heat. Add carrot, bell pepper, and green beans. Sauté for 4 to 5 minutes until vegetables are crisp-tender. Season lightly with salt.
06 - When meatballs are finished, transfer them to a bowl and toss gently with two-thirds of the firecracker sauce until evenly coated.
07 - Arrange jasmine rice on plates, top with firecracker meatballs, and serve sautéed vegetables on the side. Drizzle remaining sauce over meatballs. Garnish with sesame seeds and additional scallions.
