Pepperoni
The term pepperoni is a corruption of peperoni, the plural of peperone, the Italian word for bell pepper. The first reference using pepperoni to refer to a sausage dates to 1919.[3] Throughout continental Europe with the exception of France, peperone is a common word for various types of capsicum, including bell peppers and a small, spicy and often pickled pepper known as peperoncino or also sometimes peperone piccante peperoncini or banana peppers in the U.S
