Crunchy "natural" PB (the kind where you have to mix the oil into it) on a slice of good white sourdough, with thinly sliced cheese of your choice and homemade bread-and-butter pickles.
But I like it a bunch of other ways too!
When I was a freshman in HS, the school lunch makers served PB, bacon and hamburger dill pickle sandwiches ONCE. Never saw a thrash container fill up so fast. Might give one a go now, but not on your life then . . .
Do like a PB&J sammy, though it's tough to beat a liverwurst, dill pickle chips and mustard on dark rye sandwich.
