Peel and thinly slice the oranges; then, review them, removing the white filaments well. Peel and chop the onion into fine julienne and remove the bones from the prunes.
Place the dressing ingredients in a large bowl and emulsify with a blender or gradually add the oil while stirring with a fork.
Place on a serving dish or on individual plates a background of oranges and alternate, above, the chopped onion, the already clean bone plums and the chopped or toasted almonds in a fat-free frying pan. Sprinkle, water with the dressing and stir well.
