In a medium bowl add the lentils and enough water to cover them, let sit 30 minutes. Drain.
In a large pot add the olive and minced garlic, chopped onion and beef, brown the beef, then add the broth, puree, chopped carrots, celery, lentils and spices.
Bring to a boil then lower and simmer (not fully covered) for 45-60 or until the lentils are tender. Serve immediately. Enjoy!
Notes
Depending how much the soup thickens, you may need to add extra broth or water.
