Which sandwich is the cheapest option listed?

The Quarter sandwich is recognized as the cheapest option among the choices provided due to its simpler composition and smaller portion size compared to the other sandwiches. The Double Quarter, for instance, features two patties, which inherently increases the cost due to the extra meat. The Chicken Sandwich typically has additional preparation and ingredients, like a breaded chicken patty, which also drives up the price. Similarly, the Texas Patty Melt includes extra components such as grilled onions and cheese between slices of bread, contributing to a higher price point. In contrast, the Quarter sandwich offers a straightforward and economical option, making it the most budget-friendly choice available in this selection.
