What main ingredient is found in the Crab Cake Sandwich apart from crab?

The Crab Cake Sandwich includes arugula as a key ingredient alongside the crab. Arugula is often used in sandwiches for its peppery flavor and vibrant green color, which adds both visual appeal and a fresh taste to the dish. Its slightly bitter profile complements the sweetness of the crab, enhancing the overall flavor experience of the sandwich.

In addition to its taste, arugula also contributes to the health profile of the meal, providing vitamins and minerals. This combination of flavors and textures is what makes the Crab Cake Sandwich a popular item on the menu. Other options, while potentially interesting additions in different contexts, do not play a significant role in this particular dish.
