Which salad is a signature item on the Olive Garden menu?

The House Salad is regarded as a signature item on the Olive Garden menu because it is a staple offering that embodies the restaurant's emphasis on fresh ingredients and a classic Italian dining experience. This salad features a medley of mixed greens, tomatoes, olives, and pepperoncini, topped with a creamy Italian dressing. It is often served alongside every entrée and is a defining characteristic of the Olive Garden's commitment to providing guests with a home-style meal.

The other salad options, while popular, do not hold the same significance in the Olive Garden's identity. The Caesar Salad is well-known and frequently ordered, but it is not unique to Olive Garden, whereas the Greek Salad and Spinach Salad are not prominently featured or identified with the brand's core menu offerings. The House Salad remains a symbol of the Olive Garden experience, making it the correct choice in this context.
