In a medium bowl place all the meatball ingredients except the oil and mix with your hand until combined.  Be careful not to over mix or the meat will be tough.  Roll meat into balls the size of a golf ball.  You should have about 25.

Heat the oil in a 12" frying pan on medium heat.  Place half of the meatballs in the pan.  Cook for about 1-2 minutes and turn.  Do that until the entire meatball is cooked and the internal temp is 165 degrees F.  

While the meatballs are cooking, place pineapple juice and soy sauce in a small sauce pan over medium heat.  Mix the sugar and cornstarch in a small bowl until it is all combined.  When the pineapple juice comes to a boil, add the sugar mixture and stir until it thickens.  Set aside.

Once all the meatballs are done, pour the pineapple sauce over them and toss until they are completely coated with the glaze.  Place on a serving platter with toothpicks.  Enjoy!
