2 large onions with skin on. Cook these in boiling water for about 15 minutes. When ready peel, halve them, take out the centre leaving only a ring of three or four layers. Make stuffing of chopped parsley, garlic, anchovies, a little ham, half a dozen black olives and a handful of breadcrumbs. Fill the onions with the stuffing, pour a little oil on top. Bake them in a slow oven for an hour.
