From my understanding, this is NOT traditional antipasto, but it's loosely based on the antipasto salad I used to order when I lived in Grand Junction, CO, at a restaurant called Junction Square. I do not remember the exact ingredient amounts so everything's estimated, however, this does use an entire head of iceberg lettuce, so it can easily feed 3-5 I would guess. We always ate this as a main dish, and for lunch. All of the ingredients are easily found in your grocery store's deli and produce departments, and packaged cheese section. Cook time is assembly time.
