Cook sausage and the bacon in a large stockpot over medium-high heat until browned and cooked through, breaking the sausage into small pieces as it cooks.
Transfer the cooked sausage to a separate plate, reserving 1 tablespoon grease in the stockpot for later, and discarding the excess grease.
Add onions to the stockpot (with the grease), and sauté.
Add garlic, and sauté for 1 minute, stirring occasionally.
Add the potatoes, chicken stock and water, and cooked sausage (keep the bacon) and continue cooking until the mixture reaches a simmer.
Reduce heat to medium-low, and simmer for 10 minutes, or until the potatoes are tender.
Stir in the kale and cream, and simmer for an additional 5 minutes.
