Cut cucumbers lengthwise into thin slices, then into fine julienne. Halve the onion lengthwise, then slice into fine julienne. Cut the tomatoes in half lengthwise, remove the seeds and julienne. Place all of the ingredients in a bowl, combine well and let stand, covered, 30 minutes or longer. The juice will be salty and spicy, like fresh pickle juice, when ready. Store in the refrigerator up to 48 hours.
