I really loved this recipe and it went over really well with my family. I added a little bit more of the mayo and the buttermilk in order to make it more creamy, because that's how I like my pastas salad. I can't say there was very much left over for the following day though.
Very good creamy pasta salad that is a little different from the traditional which we enjoyed with chicken. I also think adding the buttermilk lowered the fat content a bit. Thanks for sharing!
