Which sandwich is the least expensive according to the prices listed?

The grilled cheese sandwich is considered the least expensive option among the choices provided. Generally, the ingredients for a grilled cheese sandwich are simple—mainly bread and cheese—making it less costly to prepare compared to more complex sandwiches that may include multiple protein options or toppings.

When looking at the other options, such as the egg sandwich, triple quarter, and bacon sandwich, these typically involve additional ingredients like meats or multiple servings, which can naturally drive up the price.

Understanding price points in a menu is crucial as it helps servers inform customers about their options while also managing the establishment's food costs effectively.
