As well as chip butties (mentioned already!) in Scotland you can get a tattie scone roll.
A tattie - potato - scone is a sort of triangular unleavened bread made with potatoes and some flour, butter and salt. https://en.m.wikipedia.org/wiki/Tattie_scone
The roll is typically slightly chewy with a squarish shape https://en.m.wikipedia.org/wiki/Morning_roll
