What I like is how Continental calls their chicken calzone everything but.
On my 1 leg earlier from IAH-SAN, they called it a chicken panini (I thought a panini was a pressed sandwich). On the return leg from SAN-IAH, they called it a chicen sandiwch (I thought a sandwich was anything between two slices of bread).
What even sealed the deal is that both times the calzone was served with a little bowl of marinara sauce.
