This soup is sooo good and so easy to make.
I use it all the time when I have leftover mashed potatoes sometimes it's a little thicker sometimes more liquid.
The leeks give it so much flavor. If you don't feel like chopping you can puree it later.
All in all amazing and you can make it low cal by using fat-free sour cream and buttermilk

My Hubby Loves this soup! its the only way he will eat potato soup now. The first time I made this I did not have the buttermilk so I subbed with whole milk and it was grate! The 2nd time was better-I had buttermilk! We skip the vinegar and chives to top it off with, we use bacon.
