This recipe for serbian sweet sauerkraut salad features diced bell peppers, onion, and celery and is dressed in a neutral oil like canola or vegetable. Compare this with an oil-free sauerkraut salad recipe. To reduce some of the tartness, you can drain the kraut and rinse it, if you desire, and then squeeze it dry. This is best if made the day before and has a refrigerated shelf life of about 2 weeks. It's perfect for picnics and cookouts because mayonnaise, a portion of food with the potential of becoming hazardous when not refrigerated, isn't used.
