Making Firecracker Meatballs is a simple and enjoyable process. Follow these steps to create an unforgettable dish:

1. Preheat Oven: Preheat your oven to 400°F (200°C).
2. Mix Meatball Ingredients: In a large bowl, combine the ground beef, breadcrumbs, chopped onion, minced garlic, grated ginger, egg, soy sauce, salt, pepper, and red pepper flakes. Mix well until all ingredients are fully incorporated.
3. Shape Meatballs: Use your hands to form the mixture into small meatballs, about 1 inch in diameter. Place them on a baking sheet lined with parchment paper.
4. Bake Meatballs: Transfer the baking sheet to the preheated oven and bake for 15-20 minutes, or until the meatballs are cooked through and golden brown.
5. Prepare Firecracker Sauce: While the meatballs are baking, whisk together sweet chili sauce, soy sauce, rice vinegar, sriracha, and sesame oil in a medium bowl.
6. Coat Meatballs: Once the meatballs are cooked, remove them from the oven and transfer them to a large mixing bowl. Pour the firecracker sauce over the meatballs, gently tossing to coat each meatball evenly.
7. Serve: Once well coated, you can either keep the meatballs in the bowl, on skewers for easy serving, or place them on a serving platter.
