Start by mixing the elements of your sauce. In a mixing bowl, combine 1 cup of BBQ sauce, 1 cup of pineapple juice, 1/2 cup of brown sugar, and 1/4 cup of soy sauce. Stir in your spices ensuring the sugar dissolves and the sauce is smooth.
Next, place frozen meatballs directly into your slow cooker. No need to thaw them!
Pour the sauce mixture over the meatballs, ensuring they are fully coated. Add one can of drained pineapple chunks to the slow cooker and give everything a gentle stir to incorporate the ingredients evenly.
Set your slow cooker to low for 4-5 hours or high for 2-3 hours. The slow cooking process allows the flavors to meld beautifully and the meatballs to absorb the sauce.
Once cooked, garnish with freshly chopped parsley right before serving for a pop of color and freshness.
