After a lengthy (around 4 hours) discussion among our roommates, we came along with a common definition of what is commonly referred to as a “sandwich”: 

- Article 1: A sandwich is a dish consisting of a container and a filling. 

- 1.1: The container must consist of one or two connected parts 

- 1.2: It must be possible to retrieve the container without destroying it 

- 1.3: The container must consist of a starchy base.

- Article 2: The sandwich must be able to be eaten in public without any non-edible third-party items (including tables, cutlery, napkins, and so on).

- Article 3: The customary way of consuming the sandwich must be compatible with the process described in Article 2. 

Note: The sandwich is culturally defined; therefore, Article 3 is based on cultural criteria. In case of doubt, Articles 1 and 2 take precedence.

Everything here have been debated from an occidental and french persoective.

Me and my roommates would be very happy to explore new perspectives and contradictions as it would force us to make a more precise definition of the sandwich

According to us, hot dog is a sandwich as it fullfill article 1 and 2
