Creating Firecracker Chicken Meatballs is straightforward if you follow these simple steps:

1. Preheat Oven: Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
2. Mix Chicken Mixture: In a large bowl, combine ground chicken, breadcrumbs, green onions, garlic, ginger, egg, salt, black pepper, and crushed red pepper flakes. Mix until well combined.
3. Form Meatballs: Using your hands, shape the mixture into small meatballs, about 1 inch in diameter. Place them on the prepared baking sheet.
4. Bake Meatballs: Bake in the preheated oven for 20-25 minutes, until cooked through and golden brown.
5. Prepare Sauce: While the meatballs are baking, in a small saucepan, combine sriracha, honey, soy sauce, and rice vinegar. Bring to a simmer over medium heat, stirring until well mixed.
6. Coat Meatballs: Once the meatballs are done, remove them from the oven and drizzle the sauce over them, tossing gently to coat.
7. Return to Oven: Place the coated meatballs back in the oven for an additional 5 minutes to set the glaze.
8. Garnish: Remove from the oven and garnish with sesame seeds and fresh cilantro, if desired.
