Maybe it's b/c I'm still practically a kid (and, a poor college student), but peanut butter and jelly sandwiches-- I LOVE them!
What is your favourite way to eat them?
Jelly? Jam? Marshmallow fluff? Honey? Banana? Bacon à la Elvis? Pressed in a panini press?
I once saw Paula Deen (I know, I know, she's trying to kill us) spread butter (go figure...) on the outsides of the bread, dip them in sugar, and cook it off. I've done this and let me say, it's fantastic. The sugar gets all burnt and you get that crunch.
