What is a common customization option for the Classic Garden Salad?

Adding extra protein is indeed a prevalent customization option for the Classic Garden Salad. Customers often seek to enhance their salads, and incorporating additional protein—such as chicken, bacon, or cheese—can significantly improve the nutritional value and flavor of the dish. This option not only caters to those looking for a more substantial meal but also appeals to individuals who may prioritize protein intake for dietary reasons.

While there are other options that may involve altering the salad, such as changing the bowl size or removing dressing options, they are generally less common or impactful in terms of overall enjoyment and satisfaction. Making it a dessert does not align with the nature of a salad and would not be a standard customization within the menu offerings. Therefore, the inclusion of extra protein stands out as the most relevant and beneficial customization that enhances the customer experience with the Classic Garden Salad.
