Saw this online and it looks like it MIGHT be the world's most delicious sandwich ever...and it's easy to make. (I found a version on Jezebel and used it as my reference - click here to see the blog).
Take two pieces of bread.
On one piece, spread horizontally: one row of Jelly (I used strawberry preserves), one row of honey, and one row of marshmallow fluff.
On the other piece, spread vertically: one row of CRUNCHY peanut butter, one row of Nutella, and one row of CREAMY peanut butter.
I even pressed it on my George Foreman grill to make it gooey! Don't ask about the sugar or calorie content...just indulge!
