Spread the bread with the peanut butter and the banana. Melt the margarine in a skillet over medium heat. Fry the sandwich, browning it on both sides.
Serve warm and immediately. Think of 'the King' while consuming.
Elvis' mom Gladys used to make him these sandwiches. He once ate nothing but these sandwiches for 7 weeks.
Note: Elvis always ate this sandwich with a knife and fork.
