Early Romans enjoyed many foods that are still popular in Italy today, including bread, olives, cheese, fish, shellfish and wine. But some staples of modern Italian cuisine, like pasta, were unknown at this time.
Ancient Romans made laganum, thin sheets of dough that may have been a forerunner of lasagna. But laganum was likely fried, rather than boiled, as pasta is today. The first clear evidence of boiled noodles in Italy dates to the early Middle Ages.
