anchovies,jalepenos and pineapple.I don't particularly like hawaiian pizza o anything that is hot and spicy o anything with anchovies.If it tastes awful,that too ruins pizza for me.
Tastless crust, greasy toppings. Like I had a pizza one time from pizza hut and even though I ate it, it really grossed me out cause it was so incredibly greasy. And generally I like pizza hut. Anyways, I also don't like seafood on my pizza, that would just ruin it for me. And onions.
