Fry circles of bread, cut one-third inch thick, in deep hot Cottolene. Sauté slices of tomato in hot butter. Drain both on brown paper. Cover each circle of bread with a slice of tomato, sprinkle with salt, pepper and a few grains cayenne. Garnish each with a slice of cucumber and the white of "hard boiled" eggs, cut in the shape of petals to represent field daisies.
