I was writing a comment the other day when I wrote a sentence similar to the one below:
You can choose one of either (Pizza, Mac and Cheese, or Spaghetti).
Obviously the choices are made-up, but the point is, this sentence should mean the same exact thing as:
You can choose either Pizza, or Mac n' Cheese, or Spaghetti.
I've heard that 'either' can be used for more than two choices, so this should be correct, at least, to my knowledge anyway.
But is it? Would you say it differently? How natural does it sound?
