Directions

1. Place the navy beans into a large container and cover with several inches of cool water; let stand 8 hours or overnight. Drain and rinse before using.
2. Cook the soaked beans in a pressure cooker in 4 cups of water for 25 minutes. Use the natural release method to release pressure. Do not drain.
3. Bring a separate pot of salted water to a boil. Add the kale and simmer until kale is bright green and tender, about 2 minutes. Drain in a strainer, and cool under cold running water. Set aside.
4. Heat olive oil over medium heat in the soup pot. Brown the linguica slices on each side, about 5 minutes. Remove from the pot with a slotted spoon and set aside. Add shallots to pot and cook until soft, about 3 minutes. Pour in a splash of chicken broth and scrape up any browned bits of sausage.
5. Return the sausage to the pot along with the beans and their cooking liquid. Stir in the chicken broth. Bring soup to a boil, reduce heat to low, and simmer uncovered for 15 minutes. Add the kale and cook about 4 minutes longer. Season with salt, pepper, and hot sauce to taste.
