What makes one Italian sub different from another? More importantly, what are the defining characteristics of the elusive perfect Italian sub?
In one man's opinion, here's what does it:
The other side of the bread should have mayonaise spread on it.
When all the ingredients are in the sandwich, the oil should be poured on. The oil should be used only lightly -- the end result should be that the bread is moistened, not that the sandwich is dripping.
Lastly, the sandwich should be lightly salted.
If there's only one layer of each kind of cold cut, you paid too much for the sandwich.
