Which green is NOT included in the Caesar salad?

The Caesar salad is a classic dish primarily made with romaine lettuce, which provides a crisp texture and a strong base for the salad. The ingredients typically associated with Caesar salads include romaine lettuce, croutons, Caesar dressing, and often toppings such as Parmesan cheese and, sometimes, proteins like grilled chicken.

Endives, on the other hand, are not a standard ingredient in a traditional Caesar salad. They have a different flavor profile and texture compared to romaine lettuce and are more commonly found in other types of salads.

While red onions and Parmesan are often included in various recipes for Caesar salads, it is the absence of endives in the traditional formulation that makes it the correct answer in this context.
