Which of the following vegetables is included as a veggie option on a cheesesteak?

The inclusion of banana peppers as a veggie option on a cheesesteak is an excellent choice due to their flavor profile and texture. Banana peppers provide a mild tanginess and a slight crunch, enhancing the overall taste of the cheesesteak without overpowering it. They are a popular addition that complements the savory elements of the sandwich, such as the meat and cheese.

While spinach, carrots, and cabbage can also be used in various sandwiches and dishes, they do not have the same traditional association with cheesesteaks as banana peppers do. Spinach tends to be softer and less crunchy, while carrots may not blend well with the other predominant flavors. Cabbage could potentially work, but it is not a classic topping for cheesesteaks. Therefore, banana peppers stand out as the most fitting and widely accepted vegetable option for enhancing the cheesesteak experience.
