A peanut butter and jelly sandwich (PB&J) consists of peanut butter and fruit preserves spread on bread. The sandwich is popular in the United States, especially among children; a 2002 survey showed the average American will eat 1,500 peanut butter and jelly sandwiches before graduating from high school. There are many variations of the PB&J, which itself is a hybrid between a peanut butter sandwich and a jam sandwich.
