Which salad is Romain/cos lettuce famously associated with?

Romaine or cos lettuce is famously associated with Caesar Salad, which is characterized by its crisp romaine leaves, traditionally topped with a dressing made from lemon juice, olive oil, egg yolks, Worcestershire sauce, anchovies, garlic, Dijon mustard, and Parmesan cheese. The unique texture and sturdy nature of romaine make it ideal for holding up against the rich, creamy dressing and the various toppings such as croutons and shaved cheese, enhancing the overall flavor and presentation of the dish.

In contrast, the other salads mentioned do not prominently feature romaine. Greek Salad typically relies on ingredients such as tomatoes, cucumber, olives, and feta cheese, often with leaves like iceberg or mixed greens. Waldorf Salad is known for its combination of apples, celery, nuts, and mayonnaise, while Nicoise Salad is composed of ingredients like tuna, eggs, and green beans, and often serves as a composed salad with varied leaf types but not primarily romaine.
