Sure there's something called Italian Green Olive Salad, but it's a much grander affair, with anchovies and capers. This is a simple thing, with just olives and celery. I'm suspecting ours is the "home" version that evolved in Italian homes on a budget.
It's very simple, diced celery with olives in their brine. You can also dice the olives if you like, but I think gathering a spoonful of celery with a big burst of olive flavor is part of the fun.
