Dosa, Appam, and Idiappam are breads, even though even in South India, if you ask for "bread" from your local grocer, they'd give you sliced loaves. We use the word bread to refer to these other staple breakfast dishes in an anglicized context, because it maps better than any other word to the meaning we want to convey. Which is why restaurant menus categorizes them under "Indian Breads", and if you accept that language is mutable and responds to how people use it, this is as good an alternative meaning as it can get.
