They're normal vegetables, but not normal pizza toppings. Just look at the menu offerings of any big US chain pizza place, deviating from that without warning is going to cause disappointment.

I'm from California, can't speak to the rest of the US... To me all except broccoli are perfectly normal pizza toppings. Not toppings I would expect to see on a Dominos pizza, but definitely to be expected on a "veggie" pizza from any independent pizza place.

I guess that counts as "normal," but that's fast food, where picky children's tastes rule. Predictability and therefore high-volume turnover of ingredients is paramount.
