What does the pan con bistec sandwich typically include?

The pan con bistec sandwich is a classic Cuban dish that is typically made with marinated steak, which is often grilled to perfection, and pickled white onions. The steak is usually seasoned and tenderized with a marinade that enhances its flavor, making it a savory and satisfying choice. The pickled onions add a tangy crunch that complements the rich taste of the beef, making this sandwich a flavorful experience.

The other options present ingredients that do not align with the traditional components of a pan con bistec sandwich. Grilled fish and avocado would belong to a different culinary tradition, while roasted vegetables and hummus would indicate a vegetarian option that is not characteristic of this sandwich. Chicken breast and tomato sauce suggests a different type of sandwich entirely, further distinguishing the pan con bistec's unique ingredients.
