Just for kicks, I Googled Peanut Butter, Banana, and Turkey Sandwich. This is as close as I could find. The picture shows turkey lunchmeat, but I think I’ll give it a try using sliced left-over turkey breast from Thanksgiving. It sounds pretty good.
While doing my Google search, I came across an interesting variation on the peanut butter and banana sandwich.
I might try one of these, too.
