Jan grew up eating peanut butter and lettuce sandwiches. Instead of the sugary sweet of jam or honey, she prefers the crunch of the lettuce. She also prefers to toast her bread first, for the added flavor of the Maillard reation. I forgot to toast the bread before adding the peanut butter to both slices of bread, so she had me put them in the toaster oven as is. The bread toasted, but the peanut butter became hot and melted. She thought that it went perfectly with the cool crisp lettuce.
