I was recently reminded of this "recipe" - again from my college days.......... stretching a nickel.
2 slices of bread
Peanut butter
Your favorite jelly or Nutella
Butter
Spread peanut butter on one side of the bread, top with jelly then the other slice of bread. Put butter on the outside of the sandwich. Place buttered sandwich in a heated skillet until each side is browned.
