quick creamy german potato salad that is made in a pressure cooker. It is take out of the "The Pressure Cooker Cookbook" by Toula Patsalis. I use lower fat turkey sausage. I have tried regular sausage in this recipe and it makes the salad too greasy. I normally dice the radishes and bell peppers in small pieces. I use about a half a pepper. I have substituted regular yellow mustard for dry mustard. Black pepper seems to be ok to use as well.
