I recently found out that tomatoes are native to the Americas and were brought to Europe by the Spanish (or the jesuits). Today tomatoes are ubiquitous in Spanish and Italian cuisine. What was "typical" Spanish/Italian food prior to the introduction of the tomatoe and how did the tomatoe come to dominate these cuisines in such a short time. Did it replace local ingredients or was it added onto existing recipes?
This happens to be one of our most frequent (if not the most) food history questions! If anyone else would like to put their oar in, please don't hesitate to do so, as More Can Always Be Said on the tomato's influence on Italian food.
For the meantime, OP, you may be interested in this previous thread on the matter, encompassing a post roundup from u/jschooltiger and an overview by u/Grombrindal18.
