Cook the bacon in a large pot over medium heat until crispy.
Remove the bacon and set it aside on paper towels, but leave a tablespoon of the bacon fat in the pot.
Add the Italian sausage to the pot.
Break it into small pieces with a spatula and cook until browned, which takes about 5 minutes.
Stir in the chopped onion and minced garlic.
Sauté them with the sausage for another 2-3 minutes until the onion becomes translucent.
Pour in the chicken broth and water.
Add the sliced potatoes, then bring the mixture to a boil.
Reduce heat and simmer for 15 minutes or until potatoes are tender.
Stir in the heavy cream and chopped kale.
Cook for another 5 minutes until the kale wilts and the soup is heated through.
