In my opinion, pineapple doesn't belong on pizza. Pizza is a classic dish that has its own unique flavor profile, and adding pineapple to it just seems like an unnecessary addition that ruins the balance of flavors. The sweetness of the pineapple clashes with the savory flavors of the cheese and tomato sauce, and the texture of the pineapple can be off-putting as well. While some people may enjoy the combination of pineapple and pizza, for me, it's just not a good fit. I prefer my pizza toppings to be more traditional, such as pepperoni, hamburger, and sausage.
