Instructions
- The day before you plan to make the soup, place the bean mix in a large bowl, add cold water to cover by 2 inches, and refrigerate overnight. The next day, drain the beans, rinse under cold running water, and drain again.
- Place the beans in a large pot with 8 cups of cold water. Bring to a boil, lower the heat, and simmer for 90 minutes. Stir occasionally.
- Meanwhile, heat the oil in a medium (10-inch) stockpot or Dutch oven over medium heat. Add the sausage and onion and saute over medium to medium-high heat for 12 to 18 minutes, until browned.
- Add the garlic, seasoning and red pepper flakes and saute for one minute.
- Add the tomatoes, wine, 4 cups of the chicken stock, salt and pepper and turn off the heat.
- Drain the beans and add two-thirds of them to the soup.
- Pass the remaining beans through a food mill, discarding the skins. Stir the bean puree and the pasta into the soup, bring to a boil, lower the heat, and simmer for 20 to 30 minutes, stirring occasionally, until the pasta is tender. Add more chicken stock if the soup is too thick.
- Stir in the Parmesan and the vinegar.
Ina adds, ladle the soup into large shallow bowls and add a swirl of olive oil, a sprinkle of Parmesan, and some basil.
