anchovies,jalepenos and pineapple.I don't particularly like hawaiian pizza ou anything that is hot and spicy ou 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.
