Pepperoni is a flavorful sausage that's usually cut in thin slices. On pizza night, you and your sister might argue about toppings: you prefer pepperoni, while she likes mushrooms and olives.
Officially, pepperoni is a variety of salami, a sausage that makes most people think of sandwiches rather than pizza. Usually pepperoni is bright red, with a peppery, smoky flavor and a soft, chewy texture. Rather than black pepper, most pepperoni is flavored with paprika, a seasoning made from sweet bell peppers. The origin of the name backs this up: it comes from the Italian peperone, "bell pepper."
