Actually the first dish (Khash) is apparently an Armenian dish originally. It is not popular in the Arab world at all aside from parts of Iraq I believe. It is present in Kuwait, Bahrain etc. under the name "پاچة" though.
Dolma is eaten across the Arab world (Mashriq) from Syria to Yemen and from Iraq to Egypt. Grape leafs are mostly used. محشي is a popular word. I don't know about the dishes origin though.
Khubz is just the Arabic word for Arabic bread. It is eaten in the entire Arab world. It is just flatbread often made in special ovens.
Goes under the name "خبز".
The only dish that is not eaten in KSA and the vast majority of the Arab world from the images posted is Masgoof which is entirely Iraqi. I have not encountered it anywhere else in the Arab world or outside of it. Also the national dish. Aside from the first dish posted.
I am still unsure if the first dish (Khash) is eaten in the Eastern Province of KSA but it might be very possible.
In general the Middle Eastern cuisine like with anything else nearly is very similar overall. Mutual influences, trade etc. has undoubtedly taken place for centuries if not millenniums although each region/country has its own specialties and rare/lesser known dishes.

Could you please post some Tunisian dishes? I am less familiar with that part of Arabic cuisine outside of Moroccan.
But showcasing Arabic cuisine from various Arab countries is an excellent idea. I am just afraid that it is going to make us hungry and those of us who live outside of the ME/Arab World will probably feel homesick for a while, LOL.
