Re:Zeps at Eve's and Lou's, Norristown, PA
The article states that it's more than a different name:
This is burdensome history for simple workingman's food - but then again, it's a heavy sandwich. Enough salami to cover a foot of wide, golden-crusted roll, enough provolone to cover the salami, thumb-thick chunks of raw onion and slabs of tomato across the whole thing. Add oregano, salt, pepper, and olive oil to taste. Hot pepper relish if desired. And that's it.
In a strict sense, the zep is little but a variation on the traditional hoagie, with no lettuce and only one meat.
