The night before you want to serve your soup, cover the beans with fresh water and let them soak until about 1 1/2 to 2 hours before your meal.
Drain them, put them in a soup pot and add the stock. Stir in everything else except the pasta and sausage, bring to a boil and let simmer until the beans are almost tender.
Add the pasta and sausage and cook until the pasta is tender. Serve with a green salad and a crusty loaf of bread.
