peanut butter and what?

A couple of weeks ago, I was reading The Four Winds by Kristin Hannah. In it the mom mentioned peanut butter and pickle sandwiches. Say what? So I googled it … and it really was a thing during the depression. No clue why. Maybe the bread was too dry? Or the peanut butter wasn’t as creamy as ours today? Any way, I made myself one for lunch the other day …. not horrible, but not delicious either ….
