I was browsing TasteSpotting (only the most fabulous, visually-stimulating food site) the other day when I saw someone had made peanut butter and jelly with cucumbers! I thought that was the strangest idea, if not even perhaps a little scary. So naturally, I had to try it for breakfast just now, yes breakfast at 1:30 pm! It's basic PB& J with slices of cucumbers and a pinch of sea salt. That's it!
The cucumbers make the sandwich so refreshing in this heat. I would even go so far as to say that the might even prevent your body from melting. I recommend giving it a try!
