Suggested by Shaker Secjwick: What do you order on your pizza?
As always, "I hate pizza" is a viable answer, too.
I'm pretty flexible about my pizza toppings. I'm not thrilled with black olives, which I don't fancy in any context, and I can pass on green peppers, which I do like raw but overwhelm other flavors for me when cooked, but otherwise I'll have what you're having.
My personal favorites are ham and pineapple, or chicken and spinach. Neither of which Iain likes, naturally.
