Procedure:
Slice the broccoli heads off from their stems and boil in sufficient salted water. Slice the onion and gently fry in a pan with some oil. Add the pine nuts, then the boiled broccoli heads. Add a little of the cooking water in which the broccoli were boiled.
Fry gently, adding the anchovies fillets which have chopped into fine pieces. Add the pepper, or a chopped fresh chili.
In a separate pan, fry the bread crumbs in some oil being careful not to burn them and to stir continuously then add to the broccoli sauce.
Boil the spaghetti, drain well and add to the broccoli sauce and allow to absorb the flavours.
Serve hot.
