I think that just listing favorite ingredients might be better, or rather listing least favorite ingredients, since pizzas with any decent quality ingredients should be fine to eat.
Not a fan of pepper, anchovies, jalapenos, eggplant, capers, pineapple, or fish. Those last two are just for pizza; I'm fine with those ingredients separate.
The key is the tomato sauce and type of cheese; secondary concern is the crust. No pizza is salvageable even with heaps of meat if the cheese is bad or the sauce is bland.
