A Thimble Tribute to the King.

Elvis Presley's Hot Peanut Butter and Banana Sandwich*
2 Tblsp. peanut butter (preferably smooth)
2 slices white sandwich bread, lightly toasted.
1 small ripe banana, mashed with a fork (about ¼ cup)
2 Tblsp. butter, melted

• Spread peanut butter evenly on 1 slice of toast, then spread mashed banana on other slice, leaving a ¼-inch border around edge.
• Close sandwich, gently pressing bread slices together.
• Fry sandwich in melted butter, turning over once, until golden brown, about 2 minutes total.
• Eat while still warm.

This sounds pretty awful to me, but the comments from people who've tried it on the various recipe websites that feature this recipe all highly recommend it.
