Step‑by‑Step Instructions for Cucumber, Onion, and Tomato Salad
Step 1: Prepare the Vegetables
Start by washing and drying your cucumbers, tomatoes, and onions. Slice the cucumbers into thin rounds, dice the tomatoes into bite-sized pieces, and thinly slice the onions. Aim for even cuts to ensure a pleasant presentation in your Cucumber, Onion, and Tomato Salad. Combine all the chopped vegetables in a large mixing bowl, allowing their vibrant colors to mingle.
Step 2: Make the Dressing
In a separate bowl or a jar with a lid, whisk together your vinegar, olive oil, sugar, salt, and cracked pepper. If you’re using a jar, secure the lid and shake vigorously until the sugar has fully dissolved. This zesty dressing will add a delightful tang to your Cucumber, Onion, and Tomato Salad, harmonizing all the flavors beautifully.
Step 3: Combine Ingredients
Pour the freshly made dressing over the mixed vegetables in the large bowl. Using a wooden spoon or spatula, gently toss the ingredients together until the vegetables are evenly coated. This step should take only a minute or two; be careful not to mash the delicate tomatoes while mixing.
Step 4: Chill and Meld Flavors
Cover the salad with plastic wrap or a lid and place it in the refrigerator. Allow the Cucumber, Onion, and Tomato Salad to chill for at least 15-20 minutes. This resting period is crucial as it lets the flavors meld, enhancing the taste and making it even more refreshing when served.

Once chilled, give the salad one last gentle toss to redistribute the dressing. Serve the Cucumber, Onion, and Tomato Salad in a large bowl or on individual plates. It can be enjoyed chilled or at room temperature, making it a perfect side for summer barbecues or any healthy meal on the table.
