- Cut potatoes into ½ inch cubes or slices. Dice onions. Chop celery and carrots if using. Olive Garden doesn't used celery and carrots but I love adding them to any soup.  
- In a dutch oven or large soup pot, brown your italian sausage. Remove from pot once browned.  
- Add the vegetables (except for kale potatoes!) to the pot and season with salt, pepper, and garlic powder. Allow to cook for 3-5 minutes until veggies start to soften. Once softened add in the meat, potatoes, chicken stock and water. Cover with a lid and cook on medium heat until the potatoes are tender.  
- Add in the kale and half and half. Cook for 10 minutes until kale is tender. Serve with parmesan cheese and breadsticks.
