Preheat the oven to 400*F, and adjust the oven rack to the middle position
Line a large, rimmed baking sheet with parchment paper and set aside
Place all of the meatball ingredients in a medium bowl
Use your hands to combine them well, but no need to over-mix
Shape the mixture into approximately 16 meatballs
Arrange the meatballs on the prepared baking sheet
Bake them until they are cooked through, about 12 to 15 minutes
When the meatballs are done, prepare the sauce
Combine all the sauce ingredients in a small bowl and whisk well
Pour the sauce into a large skillet over low heat, whisking until it begins to boil
Cook 30 to 60 seconds, until the sauce thickens
Turn the heat off immediately
Gently toss in the meatballs, coating well in sauce
Top off with fresh scallions and sesame seeds
Enjoy!
