01 - Preheat oven to 430°F and line a baking sheet with parchment paper.
02 - Combine ground meat, egg, breadcrumbs, garlic, scallions, soy sauce, ginger, salt, and black pepper in a large bowl. Mix just until incorporated. Form into 16 to 20 evenly sized meatballs and arrange on the prepared sheet.
03 - Bake meatballs for 18 to 20 minutes, turning once halfway, until well browned and cooked through.
04 - While meatballs bake, rinse jasmine rice thoroughly under cold water until runoff is clear. Combine rice and measured water in a saucepan, bring to a boil, then cover and reduce heat to low. Simmer for 12 minutes, remove from heat, and let stand covered for 5 minutes. Fluff rice with a fork.
05 - In a small bowl, whisk together sriracha, mayonnaise, honey, soy sauce, rice vinegar, and sesame oil until completely smooth. Set aside.
06 - Heat vegetable oil in a large skillet over medium-high. Add carrot, bell pepper, and green beans. Sauté, stirring, for 4 to 5 minutes until just tender yet vibrant. Season lightly with salt.
07 - Transfer baked meatballs to a clean bowl and gently toss with about two-thirds of the prepared firecracker sauce until evenly coated.
08 - Serve meatballs over steamed jasmine rice, with sautéed vegetables on the side. Drizzle with remaining sauce and garnish with sesame seeds and fresh scallions.
