Which meal can you serve as a sandwich meal during a long flight?

The first meal is the most appropriate choice for serving as a sandwich meal during a long flight because it is typically designed to provide passengers with a satisfying and substantial start to their journey. Serving a sandwich as this meal option allows for convenience, portability, and ease of consumption, which can be crucial in a restricted environment like an airplane.

The first meal often caters to passengers' immediate hunger after boarding, making a sandwich an ideal choice since it can be easily prepared ahead of time and served quickly. Additionally, sandwiches can accommodate a variety of filling options to cater to different dietary preferences, ensuring that passengers have something to enjoy right at the beginning of their trip.

Other meals may not be suited for sandwich presentation due to their complexity or the nature of the serving style, which might focus more on plated dishes or simpler meals later on during the flight. Thus, starting with a sandwich for the first meal makes practical sense, aligning with the initial dining experience on a long flight.
