Preheat your oven to 425°F (220°C) and line a baking sheet with parchment paper or lightly grease it with cooking spray.
Combine all meatball ingredients in a large bowl. Use clean hands to gently mix everything together until just combined. Avoid overmixing as this can make the meatballs tough.
Shape the mixture into meatballs about 1.5 inches in diameter (about the size of a golf ball). You should get approximately 20-24 meatballs.
Arrange the meatballs on the prepared baking sheet, leaving a little space between each one.
Bake for 15-18 minutes until the meatballs are cooked through and register 165°F (74°C) on an instant-read thermometer.
While the meatballs are baking, prepare the sauce. In a medium saucepan, combine honey, soy sauce, garlic, rice vinegar, and sriracha.
Bring the sauce to a simmer over medium heat and cook for 2-3 minutes until it starts to reduce slightly.
Add the cornstarch slurry to the simmering sauce and whisk continuously until the sauce thickens, about 1-2 minutes.
Once the meatballs are done, toss them in the sauce until evenly coated. You can either add the meatballs to the saucepan or pour the sauce over the meatballs in a bowl.
Garnish with sesame seeds and sliced green onions before serving hot.
