Preheat the oven to 425°F and line a large baking sheet with parchment paper.
Add all the ingredients to a large mixing bowl and mix with your hands until very well combined.
Immediately form the meat mixture into 36 to 48 balls, depending on how big or small you like your meatballs, and place them onto the reserved cookie sheet.
Place the meatballs in the oven and cook for 10 minutes at 425°F, then lower the temperature to 350°F and continue cooking for about 20 minutes, until the meatballs are cooked through and crispy and golden brown all around.
Transfer the cooked meatballs to a serving dish and garnish with a few pieces of fresh pineapple and fresh parsley, if desired.
