No, seriously. Is this chicken or fish?

In light of the recent break-up of power couple Nick and Jessica, I found myself seriously pondering what the hell I was eating for lunch. We had ordered some sandwiches for a meeting today, and of course, helped ourselves to the tray before we delivered it to the conference room. My sandwich was either tuna salad or chicken salad, BUT I HAVE NO IDEA WHICH. There was so much mayonnaise (BARF) on it, that any fishy-meaty flavor was completely masked.
