The Testaccio covered market is the best everyday food market in Rome — a modern, clean space in the neighbourhood that was once the city's slaughterhouse district, where Roman cooking traditions are strongest. The stalls sell excellent vegetables, meat, cheese, bread, and prepared food at prices considerably below the tourist-zone equivalents.
Several stalls inside sell prepared food for eating on the spot: supplì (fried rice balls), porchetta sandwiches, pasta dishes, and offal for the adventurous. This is where Romans shop and eat lunch, which is the surest indication of quality.
