Which of the following sandwiches are served fully covered?

The sandwiches that are served fully covered typically refer to those that have a top layer of bread or another type of covering to completely enclose the fillings. In this case, the combination of sandwiches listed includes items that are known to be prepared in a way that fully encapsulates their ingredients.

The Cheesesteak is a classic sandwich with fillings normally enclosed by a hoagie roll, offering a complete coverage of meat, cheese, and often sautéed vegetables. The Teriyaki sandwich, often presented in a similar style, has a top layer that covers the savory chicken or beef combined with teriyaki sauce. The Cordon Bleu features a breaded chicken cutlet, typically enclosed in a sandwich format that makes it fully covered. Finally, the Pizza sandwich option includes a top covering that merges the ingredients, similar to how pizza is prepared, making it fully encased.

This combination reflects sandwiches that are consistently served in a format that provides full coverage, aligning with the expectation of such dishes in a traditional sense. The other combinations might include sandwiches that could have open-faced styles or different presentation methods that do not conform to being fully covered.
