Boil fresh beans in water until tender (approx. 1-2 hours). Drain and put through a food processor keeping the water and about 1/4 of the whole amount of beans. Heat the olive oil in a large saucepan and add the onion, prosciutto, celery, garlic, sage, marjoram and nutmeg.
Sauté gently and when the onion starts to brown add the tomatoes, salt and pepper. Simmer for about 15 mins, until the mixture is well blended. Add the bean purée with a little of its own water. Mix well before adding the wheat. Simmer for about 40 mins. adding more bean water as the soup thickens. Add the whole beans and allow simmering for another 10 mins.
Serve with extra-virgin olive oil drizzled on top.
Note:
If fresh beans are not available, you may use dry beans. Soak the beans overnight, rinse in fresh water and boil for 45 minuets.
