What kind of food and drinks did pompeians eat?

There were many foods in Pompeii. Some examples of dishes are parsley in a mortarium, grapes, pomegranates, small hot rolls, duck with cucumber sauce, mussels, pine kernels, leeks with olives and dates fried in honey. Seafood was very popluar, a fish sauce was frequently used. The way this sauce was made was by drying out fish (by letting them lie in the sun for days) then squeezing out the sauces. Honey was also a very popular food. Vegetables used were leeks, beets and carrots. Stuffed meat was very common as well: stuffed hare, stuffed cow's udder, etc. Sweet foods were used as dessert.

The names of the meals at dinner time were: gustatio(entree), prime mensae (main course) and secunde mensae (dessert). Bibenda was drinks, and convivia was entertainment, which often accompanied a meal. Breakfast was merely a slice of bread and a glass of water. Lunch was eaten at about midday and was of fish or meat, followed by fruit. A very, very popular meat was dormouse.

That's pretty much all I know. I hope I helped a little!
