01 - Preheat oven to 430°F (220°C). Line a baking sheet with parchment paper.
02 - In a large mixing bowl, combine ground beef or pork, egg, breadcrumbs, minced garlic, scallions, soy sauce, grated ginger, salt, and black pepper. Mix until ingredients are just incorporated.
03 - Portion mixture into 16 to 20 equal-sized balls. Arrange evenly on prepared baking sheet and bake for 18-20 minutes, turning halfway, until golden brown and fully cooked.
04 - Place rice in a fine-mesh sieve and rinse under cold water until clear. Add rinsed rice and measured water to a saucepan. Bring to a boil, cover, reduce heat to low, and simmer for 12 minutes. Remove from heat and let stand, covered, for 5 minutes. Fluff with a fork before serving.
05 - In a small bowl, whisk together sriracha, mayonnaise, honey, soy sauce, rice vinegar, and sesame oil until smooth and homogeneous. Set aside.
06 - Heat vegetable oil in a large skillet over medium-high. Add julienned carrot, bell pepper, and green beans. Sauté for 4-5 minutes until vegetables are crisp-tender. Lightly season with salt.
07 - Transfer baked meatballs to a large bowl and gently toss with two-thirds of the firecracker sauce until evenly coated.
08 - Serve glazed meatballs over jasmine rice, accompanied by sautéed vegetables. Drizzle with remaining sauce, and garnish with sesame seeds and extra scallions.
