That's a grinder if you're from New England. Or a wedge, if you're from another part of New England. Or a sub, if you're from another part of New England, or a hero if you're from certain parts of Maine.

There's a thing called Pinterest and it has recipes. I ain't Eye-talian, but I make a mean eggplant parm.

I enjoyed some of it, while I found other parts gratuitous.
