Begin by thoroughly washing the romaine lettuce under cold water. Pat it dry with a clean kitchen towel, then chop it into bite-sized pieces.

Remove the stems from the pepperoncini and slice them thinly. Slice your choice of olives into halves or quarters.

In a medium mixing bowl, combine olive oil with vinegar. Add salt and pepper to taste, then whisk together until emulsified.

In a large mixing bowl, add chopped romaine, sliced pepperoncini, and olives. Grate or shave Parmesan into the bowl and toss everything gently.

Pour the dressing over the salad right before serving and toss gently to coat.

Transfer the dressed salad into a serving bowl or plates and serve immediately.
