Step 1: Prepare Your Greens. Thoroughly wash and dry the romaine lettuce. Tearing or chopping it into bite-sized pieces is key. For the best crispness, I always recommend using a salad spinner. If you don't have one, patting the leaves dry with a clean kitchen towel works just as well. Remember, a dry lettuce leaf holds onto dressing much better!
Step 2: Slice Your Vegetables. Thinly slice the red onion and cucumber. Halve the cherry tomatoes. The thinner the onion slices, the less overpowering they’ll be.
Step 3: Whisk the Vinaigrette. In a small bowl, combine extra virgin olive oil, red wine vinegar, dried oregano, garlic powder, salt, and black pepper. Whisk vigorously until emulsified.
Step 4: Assemble the Salad. In a large salad bowl, combine the prepared romaine, red onion, cucumber, and cherry tomatoes. If you have them, add some ripe black olives for an extra layer of flavor.
Step 5: Dress and Toss. Just before serving, pour the vinaigrette over the salad ingredients. Toss gently but thoroughly, ensuring every piece of vegetable is lightly coated. Avoid over-dressing; you want to enhance, not drown, the natural flavors.
Step 6: Garnish and Serve. Sprinkle with grated Parmesan cheese (if using) and a final grind of fresh black pepper. Serve immediately and enjoy the fresh, vibrant flavors of your homemade classic Italian salad recipe.
