Place frozen meatballs in a single layer on a baking tray. Bake for 15 to 25 minutes or until hot. Alternately prepare sauce, add the frozen meatballs, cover and heat on medium for approximately 25 minutes, stirring occasionally.
FOR THE SAUCE: Heat oil in a large saucepan over medium heat. Add red bell pepper. Sauté for 3-5 minutes, until starting to soften. Add the crushed pineapple, hot sauce, brown sugar, apple cider vinegar, and salt. Simmer until sauce reduces and thickens. Toss with cooked meatballs. Serve over rice.
Notes
*If you are serving young children, replace up to half of the hot sauce with water or juice from the can of crushed pineapple to make it less spicy.
