Yup. Pizza as a word to mean a flatbread with toppings pre-date the arrival of tomatoes in Europe by a good 1400 years ish.
Just like how ketchup originally was just kind of a type of plant matter derived sauce with a runny consistency that utilized a fair amount of salt. Tomato ketchup was at one point a fairly new fangled novelty as for the longest time the favoured version of it was made of mushrooms.
The tomato more than most tends to just take over certain parts of food culture and drives out all other varieties. It’s kind of the cuckoo of the food world.
