Cut the pork rind into strips.
Place into a saucepan the prosciutto (ham) cut into strips, together with oil, a chopped onion and parsley.
As soon as the onion starts to boil, add the pork rind, beans, chive, herbs, zucchini and season with freshly ground salt and pepper.
Let it simmer for a few minutes, add the water in which the beans have been boiled, cover the pan and let it cook at moderate heat.
Let it simmer, increase the heat and add pasta or rice, depending on your preference.
The minestrone should be dense at the end. Serve it with grated Parmesan cheese.
