• 2 cups chopped onions

• 3 1/2 cups (or more) water
• 2 to 2 1/2 cups cooked white beans with 3/4 cup reserved cooking liquid (see Cannellini Beans with Garlic and Sage )
• 1 large tomato, seeded, finely chopped
• 1 cup small pasta (such as farfalline)
• 1/3 cup chopped green onions (white and pale green parts only; about 2)
• Extra-virgin olive oil (for drizzling)

Instructions

1. Heat 3 tablespoons olive oil in heavy large pot over medium heat. Add onions, carrot, and celery. Sauté until all vegetables are soft, about 12 minutes. Add 3 1/2 cups water, beans with cooking liquid, and tomato and bring to simmer. Reduce heat to mediumlow and simmer 25 minutes to blend flavors, stirring occasionally. Mix in pasta; bring to boil. Cook until pasta is just tender but still firm to bite, adding more water to soup by 1/2 cupfuls if very thick, about 10 minutes. Season soup with salt and pepper.
2. Ladle soup into bowls. Sprinkle with chopped green onions, drizzle with extra-virgin olive oil, and serve.
