Necessity.

I wanted a kinda knockoff Cubano, or medianoche. But not having access to some pulled pork, had to improvise. I got some ham, pepperoni, and bread at the store yesterday. But I somehow managed to lose the ham in the twenty minutes from leaving the store to getting home. Figured "fuck it, hot dog is close enough".

Edit; I misread your question obviously. It was pretty damn good.
