Put a couple of eggs on to boil hard, while you make a thick mayonnaise sauce. Cut some beetroot, some cucumber, some cold potato, some tomato into slices. Peel your eggs, and slice them, and build up little piles of the different things, till about two inches high. Between each slice you will sprinkle grated breadcrumbs, pepper, salt, a tiny scrap of chopped raw shallot, parsley, all mixed in a cup. Finish with the rounded ends of white of egg on the top, put lettuce round and pour the dressing over it.
