PB&j?
White bread toasted or not. If not, I like it to sit awhile for the jelly to get in the bread.
Butter
Jiff or Skippy creamy, Smuckers Grape jelly.
Or,
Peanut butter, a bit of honey, and a little cinnamon mixed together, spread on bread,
a layer of a good sliced banana,
More PB mixture on a slice of bread
Put it together
Butter the outsides and toast in a hot skillet.
Pretty close to Elvis's fried peanut butter and banana sandwich,
And dam tasty with coffee or especially a hot chocolate.
