Heat the olive oil in a Dutch oven over medium heat. Add the turkey sausage, casings removed, to the skillet. Break up the meat with a spatula so it's in small crumbles.
Add the onion and a dash of crushed red pepper flakes, then cook for 3-4 minutes or until the meat is cooked and the onion is tender.
Add the carrots, potatoes, celery, and minced garlic; stir constantly for 1 minute.
Add the chicken broth then season with sea salt and freshly cracked pepper, to taste. Cover with a lid and simmer over low heat for one hour or until the potatoes and veggies are tender.
Add the kale and the drained white beans to the soup and simmer for 10 minutes. Taste and re-season if needed. Serve immediately. Enjoy.
