For the Glaze: In a medium sized saucepan over medium-high heat, combine the stock, pineapple juice, teriyaki sauce, soy sauce and brown sugar. Bring contents to a boil.
Stir in the remaining ingredients, except for the Cornstarch.
Immediately reduce to a simmer over medium-low heat, stirring occasionally. Simmer glaze, stirring occasionally, until reduced by half, about 1 hour.
Mix the cornstarch with 3 tablespoons of water. Slowly whisk into the glaze. Continue to simmer until thickened to desired consistency, about 5 additional minutes.
Meanwhile, Make the Meatballs: Preheat oven to 350 degrees F. Line a baking sheet with parchment paper for easy clean up.
In a large mixing bowl combine all of the meatball ingredients. Use your hands to mix ingredients together, being sure NOT to over mix the meatballs. For medium sized meatballs, scoop 2 tablespoons of chicken mixture into hands and form into a ball. Place onto prepared baking sheet.
Bake for 25-30 minutes, or until an instant read thermometer inserted into a meatball reads 165 degrees F.
Toss the meatballs with the glaze.
Serve immediately with additional glaze on the side for dipping.
