INTRODUCTION
A sandwich is a type of food that consists of two slices of bread that have a filling, usually consisting of a slice of meat, vegetables, cheese and other condiments.
Sandwiches are extremely versatile and can also be filled with whatever ingredient you wish, be it jam, fruit, egg, hot-dog, chocolate or ice cream.
Sandwiches can further be broken down into types depending on how they are presented. For example, an open-faced sandwich is where the slice of bread is topped with the filling and served as is. Pinwheel sandwich uses a type of flatbread that is rolled together with the filling and is cut crosswise. Sandwiches are a very popular lunch food and as snacks on-thego.
Sub got its name from the shape of the bread used to make the type of sandwich, resembling a submarine, hence the name. It is also known as a hoagie, grinder, hero, torpedo, spuckie and Italian sandwich. The main protein used in the sandwich is usually deli or cured meats like salami, ham, and mortadella. It is served with tomatoes, bell pepper, onions, pickles, olive oil, olives and provolone.
