Dad’s Famous Sweet and Sour Kielbasa will be the hit at any gathering. With just 4 ingredients, this is one of the simplest appetizers to make and also the most requested for every party. My Dad would cook it before going to bed and let it cook all night on low - about 8 hours. The kielbasa melts in your mouth. The cooking time listed below is for a firmer texture. If you want it softer similar to how my Dad made it, double the time on low and set it and forget it.Serves 12+.
