Preheat oven to 450 degrees F. Line a large baking sheet with parchment paper; set aside.
For the Meatballs:
In a large bowl, combine all meatball ingredients. Mix with your hands, until well combined.
Scoop mixture into 2-Tablespoon-sized balls, shaping with your hands. Place on the prepared baking sheet. Bake for 10-12 minutes, or until meatballs are completely cooked.
For the Firecracker Sauce:
In a small saucepan, whisk together all sauce ingredients. Bring to a boil over medium-high heat. Reduce to low and let simmer for 8-10 minutes, stirring frequently. Remove from heat. Let sauce cool slightly (it will thicken as it cools).
Dip each individual meatball into sauce, and place on a baking sheet or wire rack. Or, brush meatballs with the sauce. Serve warm as-is, or as lettuce wraps.
