To start out, you are going to want to get out a large pot and over medium high heat, add your sausage and your diced onion.
When the sausage and onion are totally cooked through, add the minced garlic and let it cook only a minute or two, or until fragrant.
Add your chopped potatoes to the pot.
Add the salt, pepper, and broth. Turn up the heat and bring the liquid to a boil.
Let the pot simmer for about twenty minutes or until the potatoes are soft.
Prep your cornstarch slurry by mixing together 3 tablespoons of water and 1/4 cup of water. Add it to the pot and stir.
Prep your kale by removing most of the stems and chopping the leaves as much as you can. Add the leaves to the pot and push it down to let the liquid cover it.
Add the heavy whipping cream and stir in until just combined.
Serve immediately. ENJOY!
