Arrange the lettuce leaves on a large platter or in a shallow bowl. Shortly before serving, toss the beans with the shallots, spoonfuls of vinaigrette, and salt and pepper. Baste the tomatoes with a spoonful of vinaigrette. Place the potatoes in the center of the platter and arrange a mound of beans at either end, with tomatoes and small mounds of tuna at strategic intervals. Ring the platter with halves of hard-boiled eggs, sunny side up, and curl an anchovy on top of each. Spoon more vinaigrette over all; scatter on olives, capers, and parsley, and serve.

*Basic Vinaigrette Dressing
This is a bare-bones recipe for the simple all-purpose vinaigrette, which you will vary as you wish. Its beauty lies solely in the quality of your ingredients. Note that you will so often see proportions of 1 part vinegar to 3 parts oil, but that can make a very acid, very vinegary vinaigrette. I use the proportions of a very dry martini, since you can always add more vinegar or lemon but you can't take it out.
1/2 tablespoon finely minced shallot or scallion (I use 1 clove garlic)
1/2 tablespoon Dijon-type mustard
1/4 tsp salt
1/2 tablespoon freshly squeezed lemon juice
1/2 tablespoon wine vinegar
1/3 to 1/2 cup excellent olive oil, or other fine, fresh oil
Freshly ground pepper
Either shake all the ingredients together in a screw-topped jar, or mix them individually as follows. Stir the shallots or scallions together with the mustard and salt. Whisk in the lemon juice and vinegar, and when well blended start whisking in the oil by droplets to form a smooth emulsion. Beat in freshly ground pepper. Taste (dip a piece of the salad greens into the sauce) and correct seasoning with salt, pepper, and/or drops of lemon juice.
