Start by washing your romaine lettuce under cold water, ensuring it's crisp and clean. Chop the lettuce into bite-sized pieces and place them into a large salad bowl.

Thinly slice the shallots and add them to the bowl with the chopped romaine. Grate the Parmesan cheese and combine both with the lettuce.

In a jar or mixing bowl, combine the lemon juice, olive oil, kosher salt, and black pepper. Blend until thoroughly mixed.

Drizzle the dressing over the salad ingredients and gently toss the salad to coat all the ingredients evenly.

Once well mixed, serve immediately or refrigerate for up to three days. Enjoy!
