Heat oil in a deep pot over medium high heat. Add potatoes and onions, cover and cook 5 minutes, stirring occasionally.
Add garlic, bay leaves, and kale to the pot. Cover pot and wilt greens 2 minutes. Season with salt and pepper. Add beans, tomatoes, chourico, and broth to the pot and bring soup to a full boil. Reduce heat back to medium and cook 5 to 10 minutes longer or until potatoes are tender.
Serve soup with hunks of crusty bread and butter.
Cook's Note: If you are in Mystic, ask for cherise (phonetic pronunciation), if you want to sample the chourico.
