I have put PB on Raisin bread... I just don't buy raisin bread often.
I used to go to the trouble of mixing it with honey, but now I'm lazy and often want it with just jam/jelly. I really like the Almond butter mixed in, and adding honey to THAT is just and extra step.

I know several people.......including my wife... who add banana. I'm not sure why I never tried that. It's probably ok... but I really don't need to discover another treat that I like. Too many already.
