Practically anything vegetables so things like onions, olives, and peppers. And mushrooms. Gross. I don't mind spinach and artichokes but peppers but the four I previously mentioned are the bane of my existence. I hate eating pizza with any of that stuff because it's so much work to go through to pick it all off. Onions are awful because they blend in really well with the sauce, dough, and cheese so I always end up accidentally eating one and it's nasty. D:
