Back when I was a HS freshman, the school lunch folks served up PB, bacon and dill pickle slices on toasted bread sandwiches one time. Lots of those sandwiches never saw anything but the trash bin. Lots of hiungry kids that day. PB and bacon would be doable - lost me at cheese and grilled onions . . . or dill pickle slices.
Different strokes for different folks, I guess. YMMV
