This is a Jewish Sephardic dish which is quite similar to the Turkish "burak." (You can also consider it the Sephardic equivalent of the Ashkenazic knish.) Burekas can be prepared with various types of dough: strudel dough (thin leaves; most traditional), rising dough, or with types of prepared dough found in the market. Typical fillings include potato, soft white cheese, spinach (sometimes spinach and potato), and mushrooms. This is a dish served on festive occasions, but also widely sold on Israeli street corners. To be tasty, it must be served hot and fresh.
