Add all sauce ingredients into a 1-Cup liquid measuring cup, whisk together, and set aside.
Mix all the meatball ingredients in a 1-qt mixing bowl. Refrigerate for 30 minutes to let the flavors combine. This step isn't required if you're in a hurry.
With meatball mixture, form into 1 tablespoon-sized meatballs. You should have 16 meatballs.
In a medium frying pan, add 1/2 teaspoon neutral oil and add meatballs to the cold pan.
Heat the pan on medium-high heat. Cook, turning meatballs every 2 minutes for browning, for about 8 minutes.
Turn the temperature to medium heat, cover, and cook for 3 minutes. Remove meatballs from the pan and drain any fat.
Whisk the sauce ingredients together again. In the same pan, add the sauce ingredients, scraping up the brown bits from the bottom of the pan.
Turn heat to medium-high and cook until sauce thickens, about 1-2 minutes.
Turn the heat to medium-low. Add pineapple tidbits to the pan and stir. Add the cooked meatballs and gently stir. Cover and let flavors combine for 5 minutes.
