Once again, Pompeii brings ancient Roman life to life. I found this 2005 article on Pompeii on LiveScience: "Researchers have tried to bring back to life the city's food chain by replanting, in the restaurant's garden and in other open spaces throughout the city's ruins, the fruits and vegetables that were part of the Roman diet -- figs and olives, plums and grapes, as well as broom, bramble, poppy and mallow."
The really groovy part? They have recipes for a peach and cumin appetizer/dessert, roasted celery dessert (?!), and a sort of Roman Pork Wellington with ricotta side dish. Yum yum! Perfect for unit studies on the Romans or anyone else who is gastronomically adventurous. Buon Appetito!
