If you wanted a reason to eat a peanut butter and jelly sandwich, now is the time: April 2 is Peanut Butter and Jelly Day. We don't question these food holidays; we just eat what they tell us to. For more PB&J goodness, check out our primer on jams and jellies and read our Peanut Butter and Jelly Report where we taste tested different brands of peanut butter. And if you want to kick things up a notch, make your sandwich the extreme way.
