1. Preheat oven to 400°F (200°C) and line a baking sheet with parchment paper.
2. In a bowl, mix ground beef, breadcrumbs, egg, minced garlic, soy sauce, parsley, salt, and pepper. Form into 1-inch meatballs and arrange on the baking sheet.
3. Bake for 15-18 minutes, until cooked through.
4. While the meatballs bake, prepare the sauce. In a saucepan over medium heat, combine honey, soy sauce, and garlic. Bring to a simmer.
5. Stir in the cornstarch mixture and cook until the sauce thickens.
6. Toss the cooked meatballs in the sauce until fully coated.
7. Serve warm, garnished with chopped chives.
