PASTA AND BEAN SOUP

Steps:

• Heat olive oil in a large heavy-bottomed pot over medium heat. Add prosciutto and cook, stirring, until prosciutto begins to render its fat, about 4 minutes.
• Add carrot, onion, celery and garlic. Season with salt and pepper, and cook, stirring, until softened but not browned, about 5 minutes. Add tomato paste, stir to coat other ingredients, and cook for 2 minutes. Add broth, one quart water and potatoes. Raise heat to high and bring to a boil, then lower heat and simmer until potatoes are very soft, about 25 minutes. Transfer potatoes to a bowl and mash them.
• Return potatoes to pot and stir them into soup. If not serving immediately, let cool, cover and refrigerate for a few days or freeze for up to 1 month. Reheat before proceeding.
• Add beans and pasta. Cook over medium heat until beans are warmed through, about 5 minutes. Stir in rosemary, crushed red pepper and cheese. Taste and adjust seasoning with salt and pepper, if necessary.
• To serve, ladle some soup into each of 8 bowls. Top with more cheese and a drizzle of extra virgin olive oil.
