  • 32 oz frozen pre-cooked meatballs (50 meatballs)
  • 20 oz pineapple tidbits (just 1 can, drain and SAVE the juice!)
  • 1/2 green bell pepper chopped
  • 1/2 red bell pepper chopped
  • 1 cup canned (reserved) pineapple juice
  • 3/4 cup light brown sugar packed
  • 3 tablespoons cornstarch
  • 1/2 cup apple cider vinegar
  • 2 tablespoons ketchup
  • 1 1/2 tablespoons soy sauce


  • Place the frozen meatballs in a large crock pot. Pour the drained crushed pineapple overtop of the meatballs, followed by the red and green chopped peppers. *
  • In a medium sized bowl whisk the reserved pineapple juice, brown sugar, cornstarch, apple cider vinegar, ketchup, and soy sauce. 
  • Pour the sauce into the crockpot. Stir so that the meatballs are mixed in and covered in the sauce. 
  • Place lid on the slow cooker and cook on low for 5-6 hours, or on high for 3-4 hours.
  • Serve over rice and garnish with sliced green onions. 


  • The recipe says 1/2 of a red and green bell pepper. You can use the full peppers if you'd like! Especially if the peppers are really small, use the full thing.
