wash and chop up the vegetables into small cubes aiming for similar sizes (the pumpkin will become mush) and dice the pancetta
optionally fry the diced pancetta that will go into the soup at this point in a separate fry pan (if you plan to fry some later as garnish)
add all ingredients (except the water, chickpeas, parmesan) and add a generous amount of olive oil
once cooked, add hot water to just cover the above (too much and it will be too thin)
after 10 minutes of simmering, add the chickpeas and parmesan
simmer for another 10 minutes
garnish with further grated parmesan +/- fried diced pancetta
