Soak the dried white beans in water overnight and drain.

Remove the large ribs of the kale and slice the leaves into very thin strips.

Place the sliced kale in a bowl of cold water for 1 hour.

Drain the kale well.

In a 8 qt soup pot, saute the onions in the olive oil until softened.

Add the drained kale, chicken stock, drained beans, linguica sausage, and grated potato to the pot.

Bring the soup to a simmer, then cover and cook for 1 1/2 hours.

Taste the soup and adjust salt and pepper as needed.

Serve hot.
