Preheat oven to 400°F (200°C) and line a baking sheet with parchment paper.

In a large bowl, combine ground turkey, panko, egg, green onions, half of the minced garlic, and half of the grated ginger until just combined.

Form the mixture into approximately 16 one-inch meatballs and place on the prepared baking sheet.

Bake for 18 minutes or until the internal temperature reaches 165°F (74°C).

While meatballs bake, combine soy sauce, water, honey, rice vinegar, sesame oil, remaining garlic, and remaining ginger in a small saucepan over medium heat.

Bring the sauce to a simmer, then whisk in the cornstarch dissolved in a teaspoon of water; cook for 2 minutes until thickened.

Remove meatballs from oven and toss in the thickened glaze until evenly coated.
