What are these called where you are?

From Fife so these are rolls. Roll on sausage, roll on bacon etc. Heard them called different things in different parts of UK.
I'm in Connecticut, USA. If that's meant to be eaten with butter or used to sop up gravy, it's a roll. If you slice it in half and put a patty or other protein filling in it, it's a bun.
