What type of salads can guests customize at Saltgrass?

Guests at Saltgrass have the opportunity to personalize their salad experience, specifically by adding additional proteins to any salad. This flexibility allows for customization based on individual preferences, dietary needs, or hunger levels, making the dining experience more fulfilling. Offering the option to enhance salads with different proteins caters to those looking for a heartier meal or looking to increase the nutritional value of their salad.

The other options suggest limitations that are not reflective of the restaurant's approach to salads. Pre-packaged salads imply a lack of customization, while stating that salads cannot be customized altogether overlooks an essential feature of the menu. Mentioning only dressing options ignores the broader customization possibilities available to guests. Overall, the answer reflects Saltgrass's commitment to offering a customizable and enjoyable dining experience.
