Prepare the Vegetables: Begin by washing the cucumbers, ripe tomatoes, and onion under cool water. Dice the tomatoes into bite-sized pieces, slice the cucumbers into half-moons, and thinly slice the onion. Combine the diced vegetables in a large mixing bowl.

Whisk the Dressing: In a separate jar, combine vinegar, cracked pepper, sugar, and a pinch of salt. Optionally add water and whisk until dissolved. Add olive oil and whisk until emulsified.

Combine Vegetables and Dressing: Drizzle the freshly whisked dressing over the vegetable mix in the large bowl. Gently toss until the vegetables are evenly coated.

Chill and Meld the Flavors: Cover the salad and place it in the refrigerator for at least 20 minutes to allow flavors to meld.

Serve the Salad: Once chilled, give the salad a gentle toss and serve it in individual bowls or on a large platter.
