Corn chips a vegetable?

I was contemplating supper tonight wondering whether I had had any vegetables yet today. I had corn chips at the Mexican place today and thought maybe they were a vegetable? Corn on the cob seems like a vegetable so maybe?

Anyhow, at least this website from University of Missouri says corn chips are not a vegetable but instead a are a grain.

I guess that makes sense in the context that corn decended from grasses like a post a short while ago discusses.
