Step-by-Step Preparation Instructions
Step 1: Prep the Fresh Produce
Wash all vegetables thoroughly under cold water. Slice the cucumbers and onions thinly, and chop the ripe tomatoes into uniform pieces. Combine all the cut vegetables in a large glass mixing bowl. 
Step 2: Whisk the Vinegar Dressing
In a separate medium bowl or measuring cup, whisk together the apple cider vinegar, extra virgin olive oil, cold water, sugar, sea salt, and black pepper until the sugar dissolves completely.
Step 3: Combine and Coat
Pour the marinade directly over the prepared vegetables. Toss gently with large wooden spoons to ensure every slice of cucumber, onion, and tomato is evenly coated in the dressing.
Step 4: Marinate and Chill
Cover the bowl tightly with plastic wrap or a lid. Place it in the refrigerator for at least 2 hours before serving, tossing once or twice to allow the tangy flavors to soak into every bite…
