Reconstituted Onions

One time during my college years, I was studying with a classmate at the Tivoli Student Union. We decided to take a break and get some food in the lower level of the building. My study-mate, named Jen, couldn't decide what to eat, but there really wasn't much of a choice to begin with. So, Jen decided to go to McDonald's. She wasn't a big fan of onions, and asked me if the hamburgers had onions on them. I hadn't enjoyed a hamburger from MickeyDs in a long time, so I wasn't quite sure if they put onions on them. Jen decided to ask the person at the counter if onions were, indeed, on the hamburger. She returned empty handed, and I assumed that the hamburgers contained onions. Me: So, I take it they had onions on them? Jen: When I asked the guy he said, "Yeah, but they're reconstituted." That is a mighty big word, must have been a psychology major. And, how is it that he made it sound that reconstituted onions are less of an onion than a non-reconstituted onion?
