If you prepare the beans, but give it more liquid, broth, bean water, or just water, you will get a memorable soup of beans and vegetables.
first, prep the veggies
second, brown pancetta slowly. reserve meat, leave fat in pan
third, saute onions and leeks soft, then add carrots and turnips, & sweat soft
fourth, saute mushrooms separately
