Which upsell option is available for the steamed broccoli?

The correct answer, cheese, is an upsell option available for steamed broccoli on the Saltgrass menu. This option enhances the flavor and appeal of the broccoli by adding a rich, creamy texture and savory taste that complements the vegetable well. Upselling cheese not only makes the dish more indulgent but also adds nutritional value, appealing to guests looking for a more hearty side.

Choosing this upsell reflects an understanding of how additional ingredients can enhance a guest's dining experience, making the broccoli more enticing. Other toppings or enhancements, while they may complement veggies, do not provide the same level of richness and flavor depth that cheese offers in this context.
