A sweet-and-sour pineapple glaze brings a taste of the Pacific islands to these crowd-pleasing pork meatballs.
Mix pork, panko, onion, cilantro, and 1 1/2 teaspoons salt. Form into 12 balls. Chill 1 hour or up to overnight.
Heat oil in a large skillet over medium-high. Add meatballs; cook turning occasionally until browned all over, about 7 minutes. Remove meatballs.
Clean out skillet, return to medium-high. In a small bowl, whisk together pineapple juice, vinegar, cornstarch, and cayenne. Add to skillet; bring to a gentle boil. Return meatballs to pot, cook, turning a few times, until sauce is reduced and meatballs are cooked through, about 5 minutes. Remove from heat. Add pineapple chunks; toss to coat. Serve with cilantro and serrano pepper.
