Preheat oven to 400°F (200°C).
In a mixing bowl, combine ground pork, breadcrumbs, beaten egg, minced garlic, grated ginger, and soy sauce. Mix well.
Form the mixture into small meatballs and place them on a baking sheet.
Bake for 15-20 minutes, or until cooked through.
While the meatballs are baking, prepare the sauce. In a saucepan, combine soy sauce, honey, rice vinegar, sriracha, and minced garlic. Bring to a simmer over medium heat.
Once the meatballs are done, toss them in the sauce until well coated.
Serve hot, garnished with chopped green onions or sesame seeds if desired.
