Where can I find "Chicago Hard Rolls" or equivalent bread?

My SO hails from Miami, where the Publix grocery store is abundant. They make these rolls that they call "Chicago Hard Rolls". We incidentally moved to Chicago a couple years ago and have been looking for their equivalent ever since.

Now I don't necessarily think these rolls are actually from Chicago or anything, and the name is probably just a coincidence. But I was wondering if anyone here had any leads on where to find similar. Cuban rolls are close, bolillos are close bit not quite. These Chicago rolls are specifically very thin and crunchy shell on the outside/soft pull apart on the inside.
