These perfect little meatball poppers are equal parts sweet and sour. Sliced pineapple rings add a pop of color to the finished meatballs skewers and extra sweetness that will keep you coming back for more!
Position the oven rack in the top third of the oven and preheat the oven to broil. Line a rimmed baking sheet with aluminum foil and lightly coat the foil with cooking spray.
Mix the pork, cilantro, breadcrumbs, egg, garlic, ginger, cinnamon, cloves, 3/4 teaspoon salt and 1/4 teaspoon pepper in a medium bowl until just combined. Use a 1-ounce ice-cream scoop to shape the mixture into 24 balls and place them on the prepared baking sheet. Broil until golden brown and firm, 8 to 10 minutes, rotating the sheet halfway through broiling.
Meanwhile, drain the liquid from the can of pineapple into a large skillet (you should have just over 3/4 cup juice). Quarter each of 6 pineapple rings (for a total of 24 pieces) and set aside.
Add the ketchup, vinegar, honey, soy sauce and a generous amount of pepper to the skillet with the pineapple juice, whisking until smooth. Bring to a simmer over medium-high heat and cook, stirring occasionally, until reduced by about a quarter and thickened, 4 to 5 minutes. Remove from the heat, add the meatballs and toss until well coated.
Skewer 1 pineapple piece and one meatball with a food pick or toothpick and place on a serving platter. Repeat with the remaining pineapple pieces and meatballs and sprinkle with chopped cilantro. Spoon any remaining sauce left in the skillet into a bowl and serve alongside the meatballs.
