The peanut butter and jelly sandwich is a staple for children in the United States. However, peanut butter is combined in sandwiches with a variety of other spreads and foods. Many of these variant sandwiches are part of family traditions, in part because the combinations often sound unpalatable to those not raised on the food.

For example, my father occasionally made peanut butter and banana sandwiches for me when I was a kid, and I have made sure that my daughter gets the occasional peanut butter and banana (peanut butter and banana sandwiches are somewhat well-known because Elvis liked to fry and eat them). Another friend of mine is waiting for the day when he and his dad can feed his children their first peanut butter and mayonnaise sandwich, a tradition in their family. There are any number of other combinations--I'm aware of people who add honey, raisins, and tuna fish to their peanut butter sandwiches.
