Lentil Soup with a Ham Bone
Note: Use an uncleaned ham bone. When you remove the bone from the soup at the end of cooking, use two forks to shred the meat from it and add it to the soup.
Use 3 cups chicken broth, 1 cup beef broth, and 3 cups water.
Add everything to the potexcept for the lentils.No need to soften the vegetables first. They float to the surface of the soup and cook/soften in the fat from the ham bone
Bring to a rapid boil, then decrease to a simmer.
Simmer for as long as you can, at least 2-3 hours. The longer, the more flavorful your soup will be.
Add the lentils during the last 45 minutes of cooking and simmergently.
