Instructions
Heat oil in a Dutch oven over medium heat. Add the smoked sausage, diced carrots, celery, onion, minced garlic, and salt. Cook, stirring occasionally, until vegetables are almost tender and onions are translucent, about 10 minutes. Add cumin and cayenne after about 5 minutes, once vegetables begin to release their liquid.
Add the stock and rinsed lentils to the pot; bring to a boil. Reduce heat to low, cover, and simmer for 25 minutes, stirring occasionally.
Add the diced potatoes and tomatoes, cover, and continue simmering for another 15 or 20 minutes, or until potatoes are tender when pierced with a fork.
Stir in the chopped kale and cook uncovered for 3-5 minutes, until kale is wilted and the soup is heated through.
Season to taste with additional salt if needed before serving.
