Heat oven to 500°F. This temperature may seem high, but it helps the meatballs cook quickly while maintaining moisture. Prepare a 9x13 inch baking dish or rimmed baking sheet by either spraying very well with cooking spray or lining with parchment paper.

In a large mixing bowl, combine all the meatball ingredients: ground chicken, panko breadcrumbs, drained crushed pineapple, milk, soy sauce, sliced green onions, minced garlic, grated ginger, and black pepper. Mix thoroughly until all ingredients are well incorporated. Don't overmix as this can make the meatballs tough.

Using your hands or a small cookie scoop, form the mixture into meatballs about the size of a golf ball (approximately 1½ inches in diameter). Place them in the prepared baking dish or on the baking sheet, spacing them slightly apart. You should get about 20-21 meatballs from the mixture.
04 -
Place the meatballs in the preheated oven and bake for 15 minutes, or until they are fully cooked through. The internal temperature should reach 165°F when tested with a meat thermometer. The meatballs should be lightly browned on the outside.
05 -
While the meatballs are baking, make the sauce. In a large skillet or saucepan, combine soy sauce, water, brown sugar, reserved pineapple juice, minced garlic, and grated ginger. Whisk together over medium heat until the sugar has completely dissolved, about 2-3 minutes.

In a small bowl, stir together the cornstarch and 1 tablespoon of water to create a slurry. Slowly pour this mixture into the simmering teriyaki sauce while whisking constantly. Continue to simmer the sauce, stirring occasionally, until it has thickened to a glaze-like consistency, about 5 minutes.

When the meatballs are done baking, transfer them directly into the skillet with the thickened teriyaki sauce. Gently toss or stir to coat all the meatballs evenly with the sauce. Let them simmer in the sauce for 2-3 minutes to absorb some of the flavors.

Serve the meatballs and sauce over steamed white rice. Garnish with additional sliced green onions and sesame seeds if desired.
