The first time I tried a PB burger, I was unsure. It was on a menu and I asked the waiter how many people order this. He said if you order it and don't like it I will bring you something else. So I tried it and the creaminess and saltiness complimented the burger nicely, and on occasion I still have a PB burger.
I also like to make PB stuffed, bacon wrapped jalapeños on my smoker. I gave them a try based on my liking for a PB burger.
