Wikipedia: Pepperoni
Pepperoni is an American variety of salami, made from cured pork and beef mixed together and seasoned with paprika or other chili pepper.
 
Pepperoni is characteristically soft, slightly smoky, and bright red in color.[3] Thinly sliced pepperoni is a popular pizza topping in American-style pizzerias and is used as filling in the pepperoni rolls popular in Pennsylvania and West Virginia.
