My family think I'm a monster, but it was really nice. I chucked a load of parmesan on too, which really counterbalanced the sweetness of the plums nicely.
I can see it. Sweet + savory often works. I don't really care for most iterations of pineapple on pizza I've had, but I don't much care for pineapple (grilled pineapple being probably my favorite application, but still not something I ever go out of my way to order).
