Nothing beats the comfort of a slow cooker meal on a busy day. These Crock Pot sweet and sour meatballs come together with hardly any effort, yet deliver big flavor thanks to the pineapple, peppers, onions, and tangy homemade sauce. The recipe is just slightly adapted from our wildly popular dump-and-bake sweet and sour chicken, so you know it's going to be good! Serve this dish as a main course over rice or keep it warm for a tasty party appetizer.
