As a kid, I ate bologna-and-jelly sandwiches. I don't know what compelled me to make one in the first place, but for some reason I liked the combo. I probably stopped eating them when I decided against a life of celibacy. (Either that or I just realized that they're gross and I was only eating them because it raised eyebrows.)
Today, I like PB&Js, and if we have a bag of tortilla chips that are down to the crumbs, I'll sprinkle in a layer of those. They add a nice texture, and the saltiness enhances the flavor of the PB while it complements the sweetness of the jam. My wife thinks it's a little weird, but so far, so good in the no-celibacy department. ?
