Which two vegetables can be added to the Cheesesteaks?

The inclusion of mushrooms and peppers as add-on vegetables for Cheesesteaks is a popular choice because they enhance the overall flavor and texture of the sandwich. Mushrooms provide a rich, earthy taste that complements the savory steak, while peppers add sweetness and a slight crunch, along with a colorful presentation that makes the dish visually appealing.

Other options may include vegetables, but they do not traditionally accompany Cheesesteaks or contribute to the classic flavor profile. Spinach and broccoli, for instance, are more commonly associated with different types of dishes and do not align with the typical ingredients found in a traditional Cheesesteak. Onions, while they can be included in a Cheesesteak, are not paired with radishes, which are not a common topping in this context. Similarly, tomatoes and carrots do not typically feature in Cheesesteaks, where the focus is rather on melted cheese, flavorful meats, and specific sautéed vegetables.

Therefore, mushrooms and peppers are the correct and most complementary choices for enhancing a Cheesesteak.
