<p>Sergio Esposito preparing a panino all&rsquo;allesso.</p>

<p>When the new Mercato di Testaccio opened in July 2012, vendors and shoppers did not universally rejoice. Higher rents, a less convenient location, a sterile atmosphere and a competing weekend farmers&rsquo; market nearby were among the complaints. But in the two and a half years since the structure&rsquo;s inauguration, the market has proven to be a success on many counts, especially for the new opportunities it has created for vendors: Da Aretnio (Box 90) sells biodynamic wines selected by Jonathan Nossiter and wood fired baked goods from Lariano; Dess&rsquo;art (Box 66) sells Sicilian sweets and savory snacks, including cannoli filled to order and panelle, generously salted. But the single most important innovation can be found at Mordi e Vai (Box 15), where Sergio Esposito, a retired butcher, serves sandwiches and side dishes made from family recipes.</p>
