There's a restaurant near me that does a really good Chicken Tikka Masala pizza, and it has conventional cheese on it (though I'm given to understand they use a different dough for that than for their more conventional pizzas).Well there's the crux of it. Pineapple's great on pizza but not with cheese.
I recently went to an Indian restaurant that does an amazing Indian pizza, but I hadn't been in well over a decade (or two!). I was shocked to find they put cheese on it. I'd remember it not having cheese, before. I mean, paneer would've been fine, but mozzarella + spiced vegetables?
