I feel we should acknowledge Jimmy Carter’s 100th birthday in the peanut butter sandwich thread.
Happy birthday, Mr President! 
This appeared in Heloise today. Seemed appropriate to share.
The most exotic PB sandwich I had was at Beach Week in 1988. PB on bread and then covered with chex party mix. We all agreed that it was actually quite good.
Other than that, I like raisins and cinnamon on a PB sandwich.
Wow- I like the sound* of that.
*crunch-crunch
Back when I could eat sugar and carbs (which I will likely never be able to do ever again) when a standard pb&j sandwich wasn’t enough I would make it a double-decker: three slices of bread with two layers of filling.
You have good taste.
When I can find good fudge, I always get Rocky road fudge. So good.
For now, peanut butter on a corn tortilla. Mmmm. Might add cinnamon.
Oh my! 
How intriguing…
