No ground chicken here. Pure fillet.
North America, a
chicken sandwich is a
sandwich which typically consists of a boneless, skinless breast of
chicken served between slices of bread, on a bun, or on a roll. Variations of what North Americans consider a "Chicken Sandwich" include the
chicken burger or
chicken on a bun,
hot chicken, and
chicken salad sandwich. Countries outside North America generally consider a chicken sandwich to only consist of flat bread, whereas a
chicken burger is defined by the use of bread buns with chicken as part of its content.[

Just another example of usa /north america calling something different to virtually the rest of the world and thinking it's everyone else that's wrong.
You call it whatever the fuck you want but it doesn't change anything. Try calling it that somewhere else and you might not get what you wanted
