It's 8:30 AM and I want a chicken parm sub

I was doomscrolling in bed when I woke up and scrolled through a video of Irish people being introduced to a classic American chicken parm on a sub roll. (Yes, it blew their mind, as it well should.)

Now I can't stop thinking about a chicken parm sandwich. Man, if I had one right now, I would so destroy a chicken parm for breakfast.

But . . . it doesn't have to be right now. I can (probably) hold out until lunch ... or at least until the lunch spots open at 10 or 11 am.

Where in DC/Arlington/Alexandria is the best take-out chicken parm sub?
