I'm going to a friend's house for dinner on Friday, and we're having a pizza showdown. He's bringing his toppings, we're bringing our toppings, and we're going to see who puts together the best combination. This guy's a really good cook and he makes great pizza, but I'd like to see if I can't match him this time. I'm hoping the Chowhound community might have an idea for a delicious combination that will contrast what I'm up against, and maybe even taste a little better. I had the notion of doing something traditional, but doing it really well; for some reason, I also had mango in my head, but I'm not totally sold on it.
My nemesis has revealed that he's going to be doing caramelized onions, proscuitto, artichokes, asparagus, olives, and feta.
He's providing the crust, and it won't be anything unusual. Oh, and the toppings require cooking, I'd like to do that in advance before I take it over there.
What do I counter with?
