For street-cart habitués as hungry to know the source of their shawarma as they are for lunch, here’s an idea whose time has come: International Meats Local, being billed by organizers New Amsterdam Market and the Vendy Awards as the “first sustainable street meat event.” On May 6, $20 admission buys tasting portions of Solber’s pupusas, A-Pou’s Taiwanese dumplings, Eggs Travaganza’s egg sandwiches, and more, all made with humanely raised, regionally sourced ingredients from the likes of Knoll Krest Farm, Bo Bo Poultry, and Marlow & Daughters (South St. nr. Peck Slip; tickets at internationalmeatslocal.eventbrite.com).
