The Soup
Heat a large saucepan over medium heat, then add the onion, garlic, and carrots and saute for a few minutes, stirring, until the onion is soft and translucent.
Add the tomatoes, broth, water, lentils & bay leaf. Bring to a boil, then reduce heat and cook until the lentils are tender. Keep the lid partway covering the top and cook about 20 minutes, stirring every 5 minutes or so.
If using a traditional blender: Remove from heat, pull out the bay leaf, then pour into a blender cup. Let cool a bit, then add the remaining ingredients. Cover the top with a towel and pulse very gently a couple times to release the extra pressure, then blend till smooth. Adjust seasonings to your liking and blend again.
If using an immersion blender: remove the bay leaf from the pan, add the remaining ingredients to the pot and blend till smooth. Adjust the seasonings to your liking and blend again.
