Which of the following ingredients is included in the dinner salad?

The dinner salad at Saltgrass includes croutons as a standard ingredient, which adds a crunchy texture and a savory taste to the salad. Croutons are often made from bread that is toasted or baked until crispy, and they are a popular topping in many salads because they provide a satisfying contrast to the fresh greens and other vegetables. This enhances the overall experience of the salad by adding not only flavor but also a delightful crunch.

In contrast, while cranberries, walnuts, and blue cheese can be found in various salad offerings, they are not standard components of the dinner salad specifically, which is why croutons are the correct choice in this context.
