In a large stock pot, add all the ingredients, except the kale. Bring to a boil, then cover, turn down and simmer until the lentils are soft. About 30 minutes. For the last 5 minutes of cooking, add the kale. Serve immediately or refrigerate for later.
This soup should last at least a week in the fridge. It can also be frozen for up to 6 months. Enjoy!
