not much. i can only come up with combinations involving peanut butter:

pb + apples
pb + jelly
pb + bananas
pb + ramen
pb + celery
pb + celery + raisins

right now i am eating a peanut butter and jelly sandwich. they don't eat these here in sweden, and the peanut butter is imported from the US which makes it really expensive...but it's worth every mouth-foaming spoonful. thank god for bayle jr, or kellogg, or whoever it was that brought this wonderful thing into existence.
