Prep the vegetables. Chop the onion and mince the garlic. Pull the kale leaves from the stems and roughly chop them. Cut the potatoes in quarters or a grid lengthwise. Then, instead of chopping into cubes, slice them thinly so they cook up quicker.
In a large soup pot over medium heat, begin to brown the sausage, breaking it up with a wooden spoon, about 5 minutes.
When the sausage is almost done, a little pink is ok, move it to one side and add the onions and potatoes to saute on the other side in the rendered fat from the sausage. Season the potatoes with a pinch of salt and pepper. Stir each side occasionally, but not too often so each can caramelize in the hot pot. A little mixing is fine but try to keep them separate, about 10 more minutes.
When the sausage is fully cooked through and browned a bit, add the kale and garlic and stir everything together.
Add the white beans and chicken stock and simmer about 20 to 25 minutes until the potatoes are tender. You can adjust the heat down to keep it at a gently bubble, stir occasionally. Taste a potato to see if it's done!
Add the cream and herbs, simmer a few more minutes and it's ready to eat!
Serve with Parmesan cheese and crusty bread.
