Cut the eggs lengthwise and remove the yolks. Scoop out some of the pulp from the tomato halves and turn upside down to let them drain (try to remove as much water and seeds as possible without wasting too much of the pulp). Cut the cucumbers and zucchini lengthwise and remove seeds. Prepare the mayonnaise orange.
Fill the vegetable shells with the mayonnaise and sprinkle with chopped herbs and the yolks, which have been passed through a sieve. Chill. An attractive way to serve is to arrange the vegetable shells on a bed of watercress or lettuce leaves.
