Ingredients and Preparation
All varieties of this sandwich use an oblong bread roll as opposed to sliced bread. The traditional sandwich usually includes a variety of Italian luncheon meats such as dry Genoa salami, mortadella, thin sliced pepperoni, capocollo or prosciutto, and provolone cheese served with lettuce, tomato and onions seasoned with salt, pepper, oregano and olive oil. American bologna is sometimes used in place of mortadella and ham is often substituted for capicola, with prosciutto frequently omitted.
Many locations that provide catering services also offer very large 3-foot and 6-foot "Giant" sandwiches. Crusty Italian breads are preferred for the hearty sandwiches.
Vegetarian and vegan versions stuffed with soy-based ersatz meats are also popular.

Famous quotes containing the words ingredients and/or preparation:
“Copernicanism and other essential ingredients of modern science survived only because reason was frequently overruled in their past.”
—Paul Feyerabend (1924–1994)
“It’s sad but true that if you focus your attention on housework and meal preparation and diapers, raising children does start to look like drudgery pretty quickly. On the other hand, if you see yourself as nothing less than your child’s nurturer, role model, teacher, spiritual guide, and mentor, your days take on a very different cast.”
—Joyce Maynard (20th century)
