What name would you give to a food item consisting of a poultry filet situated between a sliced brioche bun?

I went to my local 7-11, and in the warm food case there were two foil wrapped products. I asked the clerk what they were and he said:

"Cheeseburgers. No, wait. Meat Burgers."

I was like...

"So, a hamburger?"

To which he replied:

"No, not ham. Meat."

Being thoroughly confused at this point because as far as I'm concerned ham is meat, albeit a different kind of meat than what a hamburger would typically contain, I said:

"I don't know what that's supposed to mean, but I'll risk it. I'll have one 'meat burger'; please."

So, I get out to my car and open this thing up, and... it's a regular ol' chicken sandwich. That poor Man must not have remembered the word "chicken". He did the best he could though, and looking back on the conversation I can definitely see how it would make sense to him.

Then I thought to myself... How would you have described it, and I'm pretty sure my special self would have said "bird sandwich" or something, haha. All of that is to say that all things considered he did a pretty good job at trying to explain to what it was.

What would you have called it?
