Remove sausage from pot and set aside.
Put the pot back on medium heat. Add the bacon, onion, and garlic. Cook until the onions are translucent, approximately 5 minutes.
Add the chicken stock and bring to a boil over high heat.
When boiling, add the potato slices. Reduce heat to medium.
Cook on a simmer over medium heat until the potatoes are just tender, approximately 20 minutes.
Add the cream, cooked sausage, and kale to the soup. Stir and simmer 5 minutes. Season to taste with salt or pepper as needed.
Cook the soup with the kale for as long as you desire based on how soft or firm you want the kale. When reheated, the kale wilts more, so you can always add kale to each serving as desired to keep it crunchy.Make this soup spicier by using a spicier Italian sausage or using more red pepper flakes.
