A deli roll is a puff pastry dough rubbed with mustard and filled with assorted deli meats (usually pastrami and turkey.)
Is this considered pas haba bekisnin? (one definition of this term is:
רבנו חננאל, מסכת ברכות דף מב. ואמר כיון שהזכיר רב ששת פת הבא בכיסנין, פירש זו הפת העשויה כמין כיסין מלאים סוכר ושקדים ואגוזים וכיוצא בהן… Rabbenu Hanan’el, Commentary to Masekhet Berakhot 42a And it says that when Rav Sheshet mentions pat haba bekisnin, he explains this as bread that is made like a type of pocket that is filled with sugar, almonds, walnuts, etc…
The above definition sounds like a pastry or "turnover". However, it defines filling with sweet items or nuts.
I'm not sure if this definition would be applied to a deli roll which seems to be shaped similarly (i.e., it is a "filled" dough.)
There is also a generally accepted rule among most current poskim stating that regardless of the shape / form, if the food is normally eaten as a meal and not a snack, one would have to wash and say "hamotzi", anyway. I'm not sure what the status of a deli roll is.
