01 - Preheat oven to 430°F (220°C). Line a baking sheet with parchment paper.
02 - In a large mixing bowl, blend ground meat, egg, breadcrumbs, garlic, scallions, soy sauce, ginger, salt, and pepper until just combined. Form into 16–20 small, even meatballs. Arrange on prepared baking sheet.
03 - Bake meatballs for 18–20 minutes, turning halfway through, until browned and thoroughly cooked.
04 - Meanwhile, rinse rice under cold water until 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, let stand covered for 5 minutes, then fluff rice with a fork.
05 - In a small bowl, thoroughly whisk together sriracha, mayonnaise, honey, soy sauce, rice vinegar, and sesame oil until smooth. Reserve sauce.
06 - Heat vegetable oil in a large skillet over medium-high heat. Sauté carrot, bell pepper, and green beans for 4–5 minutes until just tender but crisp. Lightly season with salt.
07 - When meatballs are cooked, toss gently with about two-thirds of the firecracker sauce until evenly coated.
08 - Serve glazed meatballs over jasmine rice with sautéed vegetables alongside. Drizzle with remaining firecracker sauce and garnish with sesame seeds and sliced scallions.
