In a bowl, soak the prawns in cold water for five minutes. In the meantime, clean the pineapple and cut it into cubes. Drain the prawns carefully and add them to the pineapple, then mix in the orange mayonnaise. Cut the lettuce into julienne and distribute on a serving plate; place the shrimp cocktail on top and complete with sliced tomatoes and a sprinkling of chopped parsley.
