Wylie Dufresne's Garlic Bread

We roast off several heads of garlic in foil and then put that through the food mill and blend it with some raw parsley and some butter. You get this really bright-green spread. We get some white hero rolls down the street, slice them lengthwise, toast them really well, spread the garlic butter on, hit them with some Parmesan cheese, and put them back in the toaster and get them nice and golden brown with melted cheese.
