Step‑by‑Step Instructions for Cucumber, Onion and Tomato Salad
Step 1: Prepare the Vegetables
In a large mixing bowl, incorporate chopped cucumbers, halved cherry tomatoes, and diced red onion. Use a sharp knife to ensure clean cuts, and aim for bite-sized pieces to maximize both texture and flavor. Add minced flat leaf parsley for an herbal touch, ensuring each ingredient is evenly distributed.
Step 2: Season the Veggies
Sprinkle a generous amount of salt and freshly cracked black pepper over the prepared vegetables. This simple step enhances the refreshing flavors of your Cucumber, Onion and Tomato Salad. Toss gently with a large spoon to ensure that every piece gets a taste of that savory seasoning.
Step 3: Make the Vinaigrette
In a small bowl, whisk together high-quality olive oil, tangy red wine vinegar, and minced garlic. Aim for a balanced ratio of oil to vinegar for richness and acidity. Continue whisking until the mixture is well blended, and consider adding a pinch of salt and pepper for extra depth.
Step 4: Dress the Salad
Pour the homemade vinaigrette over the seasoned vegetables in your mixing bowl. Use a spatula or wooden spoon to gently fold the dressing into the salad, ensuring that every cucumber, tomato, and onion is beautifully coated with the tangy sauce.

Squeeze the juice of a fresh lemon over the top of the salad, allowing its bright acidity to enhance the overall flavor. You can adjust the amount based on your taste preference, but a good dose will brighten the ingredients and tie the dish together beautifully.

Cover the bowl with plastic wrap or a lid and refrigerate the salad for at least 30 minutes. This resting time helps meld the flavors, making each bite even more delightful. When ready to serve, give the salad a gentle stir to redistribute the vinaigrette before enjoying your vibrant Cucumber, Onion and Tomato Salad.
