Dice a quarter of a Bermuda Onion as finely as possible. Open a can of good quality sardines and pour off most of the oil. With a fork, mash together the sardines and the onions, adding a bit of diced jalapeno or black pepper to taste. Spread on thin crisp toast.

A similar dish, using canned albacore tuna and finely chopped scallions and oil-cured black olives spread on fresh foccacia is equally toothsome, almost as good as foccacia baked with sliced plum tomatoes and anchovies on top.

Of course, mashed roasted garlic cloves mixed with olive oil and spread onn toasted peasant bread's hard to beat.
