What other fruit ( pineapple is wellknown ) would tast good on a pizza? That was the question i asked during lunch at school. The results off that class..
Passionfruit, watermelon and Strawberry were the favorite ones to be tasted.
Bad idee was kiwi, apple and cherrys.
Lemon (and/or lime) makes almost everything better when utilized properly, spicy sausage with lemon ricotta for example. I bet you could make a ridiculously delicious pizza with preserved lemon too. Lime would pair well with Mexican-inspired or Asian-inspired pizzas.
