Actually, I like the combo of PB AND pickles AND onion slices on a sandwich.
My in-laws intro'ed me to it long ago. The pickles have to be Claussen dills, sliced thin---no other pickles will work. And the PB has to be real PB, with only peanuts and salt, like Laura Scudders. None of that Jif or other stuff with sugar, hydrogenated veg oil, or other added ingredients.Try it...you'll like it.
