Fried peanut butter ? My goodness, I had never heard of that.
From PBS website no less:
Elvis Presley's Grilled Peanut Butter
and Banana Sandwich
2 slices of white bread
2 tablespoons of smooth peanut butter
1 small ripe banana mashed
2 tablespoons butter
Spread the peanut butter on one slice of bread and the mashed banana on the other. Press the slices gently together. Melt the butter (or to be truly Elvis-like, melt bacon fat!), over low heat in a small frying pan. Place the sandwich in the pan and fry until golden brown on both sides. Eat it with a glass of buttermilk.
