Start by rinsing the romaine lettuce thoroughly to remove any dirt. Cut it lengthwise into sections and then chop into bite-sized pieces. Discard the tough ends for better texture.
Place the chopped lettuce into a salad spinner and spin until completely dry. This step is important because excess water can dilute the dressing. Dry leaves also help the dressing stick better.
In a small bowl, combine olive oil, fresh lemon juice, and parmesan cheese. Mix well until slightly creamy and balanced. Letting it sit briefly helps the flavors blend beautifully.
Add the lettuce to a large bowl and pour the dressing over it. Toss gently until every leaf is evenly coated. Make sure not to overdress to keep the salad light and crisp.
Sprinkle salt and cracked black pepper on top for added flavor. Serve immediately while the lettuce is still crisp and fresh. This salad tastes best when chilled slightly before serving.
