Meanwhile, in a blender, combine the reserved beans, broth and 1/3 cup grated cheese till smooth. Add this to the skillet and stir through. Return the sausage to the skillet. Add the finely sliced kale and let the warmth of the broth soften and warm the kale through.
Taste and add salt sparingly since the sausage and cheese will have added a saltiness already. Then add in 1 tsp pepper. Taste and adjust as desired.
Finish with the chopped parsley, and more grated Pecorino if you want, and serve with toasted baguette or focaccia.
If three average sized sausages come close to 3/4 lb or so, this is fine. Use hot Italian or mild Italian sausages, as per your liking.
Feel free to use vegetable broth instead of chicken broth. Add a spoonful of my Faux Chicken Bouillon Powder for added depth of flavour.
You can replace the kale with chiffonade-ed spinach. If you use a curly kale, you wil need to let it cook longer before finishing the dish, as it needs more time to break down and soften.
You can swap out red wine vinegar for the lemon if you desire.
