What feature sets apart the "Texas Cheesesteak" from other sandwiches?

The defining characteristic of the "Texas Cheesesteak" that distinguishes it from other sandwiches is the inclusion of jalapenos and grilled onions. These ingredients contribute to the sandwich's unique flavor profile, enhancing the overall taste and giving it a Texas twist that sets it apart from a traditional cheesesteak. The heat from the jalapenos and the sweetness of the grilled onions create a combination that is not just about the meat and cheese but adds complexity to the dish, making it distinctly appealing to those looking for a more southwestern experience in their sandwich.

While other options mention ingredients and characteristics typical of sandwiches, they do not capture the essence of the specific taste that jalapenos and grilled onions provide in this particular dish.
