Lentil Soup

I was going nuts trying to come up with a lentil soup that would be close to how my mother used to prepare it. I had the lentils, the onions, the tomatoes, and a little salt ready but I knew I was missing something. After making it several times, it simply did not taste the same as my mom's, the way I knew it should. I finally called my sister Fifi and she told me that what I was missing was the cilantro. I would never have guessed. I am ok now.
