1) Add the water & sugar to a saucepan over medium heat, stirring until the sugar dissolves. Once fully dissolved, pour in the ArBol Pina Sauce and mix until smooth.
2) Add the fresh cranberries to the pan and reduce the heat to low. Simmer for 10–15 minutes, stirring occasionally, until the cranberries soften & burst and the sauce thickens into a glossy coating.
3) Bake the frozen cocktail meatballs according to the package instructions (or use your own fresh recipe). When fully cooked, transfer the meatballs to a serving dish or large bowl.
4) Pour the warm Cran-Pina sauce over the meatballs and toss gently until every piece is coated. Serve immediately, or keep warm in a crock pot on low for parties or gatherings.
