Alright, I've come up with a sandwich idea, and I know this one is gonna sound a little out there but stick with me.
First, you take some bread as usual. You can toast it, I usually do. Next, you get some peanut butter, spread it on the bread to give it a nice sticky coating. After that, grab some jelly or jam, whichever you prefer put it on top of the peanut butter - and this is the tricky part - make sure the jam does not flow past the edges of the sandwich, and then close it and eat. I like to call this a "jelly and peanut butter on bread" and it's really easy to make.
