Step‑by‑Step Instructions for Cucumber, Onion and Tomato Salad
Step 1: Combine Vegetables
In a large mixing bowl, add the chopped cucumbers, halved cherry tomatoes, and diced red onion. If you prefer a milder onion flavor, soak the diced onion in cold water for about 10 minutes before adding. Toss in the minced flat leaf parsley for a touch of freshness and color, making sure everything is evenly distributed.
Step 2: Season
Sprinkle a generous pinch of salt and freshly cracked pepper over the vegetable mixture in the bowl. This step is crucial to enhance the flavors of your Cucumber, Onion and Tomato Salad. Gently stir the ingredients with a spatula or a large spoon, ensuring that the seasoning is well-distributed throughout the salad.
Step 3: Make Vinaigrette
In a small bowl, whisk together ¼ cup of extra virgin olive oil, 2 tablespoons of red wine vinegar, and one minced garlic clove. Add a pinch of salt and pepper to the mixture, tasting as you go to ensure a balanced flavor. The vinaigrette should be smooth and emulsified, with the right hint of tanginess that will elevate your salad.
Step 4: Dress Salad
Pour the prepared vinaigrette over the vegetable mixture in the large bowl. With a gentle hand, stir the salad until all the ingredients are coated evenly in the flavorful vinaigrette. Be careful not to mash the tomatoes; you want the salad to maintain a fresh, vibrant appearance and texture while blending the flavors.
Step 5: Finish with Lemon
Squeeze the juice of half a fresh lemon over the top of the salad, adding a bright, zesty finish that enhances the overall taste. This step is essential as it adds an extra layer of brightness to the Cucumber, Onion and Tomato Salad, making every bite refreshing and delightful.
Step 6: Chill
Cover the salad with plastic wrap or transfer it to an airtight container and refrigerate for at least 30 minutes. Chilling allows the flavors to meld beautifully, creating a truly refreshing dish. When you’re ready to serve, give the salad a gentle stir to reapply the vinaigrette and bring it back to life.
