Secret Menu Items / Original Staff Creations

In Saskatoon, Sasktchewan, Canada Subway, a employee created his own original subs. He told me that he figured out the cost of the ingredients then asked his boss if he could do them. He got the okay.

One I remember was a chicken cordon bleu. (Years later, Subway came out with a limited time chicken cordon bleu sub). He had a few others. I tried the chicken cordon bleu and another. He got me to try them. They were both very good.

Has anyone came up with their own original creations? Are there secret menu items? Let's see how good or not so good they sound.
