Preheat and prep: Heat your oven to 400°F (200°C). Line a sheet pan with parchment or lightly oil it to prevent sticking.
Mix the meatball base: In a large bowl, combine ground turkey, breadcrumbs, egg, milk, garlic, ginger, green onions, salt, pepper, and sesame oil.
Use a fork or your hands to mix just until combined. Do not overmix or the meatballs will turn dense.
Shape the meatballs: Scoop about 1 1/2 tablespoons per meatball. Roll gently into balls and place on the sheet pan, spacing them out.
Bake: Cook for 14–16 minutes, or until the centers are no longer pink and the internal temperature reaches 165°F (74°C). If you prefer browning, broil for 1–2 minutes at the end.
Start the sauce: While the meatballs bake, whisk soy sauce, water, honey, rice vinegar, ginger, and garlic in a small saucepan over medium heat.
Thicken the glaze: Once the sauce simmers, stir in the cornstarch slurry.
Whisk and cook 1–2 minutes until glossy and slightly thick. Remove from heat and stir in sesame oil.
Coat the meatballs: Add cooked meatballs to the saucepan and gently toss to coat. If the sauce thickens too much, add a splash of water to loosen.
Serve: Spoon over rice or cauliflower rice.
Top with sesame seeds and green onion. Add a side of steamed greens for a full, balanced plate.
