Save the Deli is a man (David Sax) and a site (http://www.savethedeli.com), and a book (Save the Deli: In Search of Perfect Pastrami, Crusty Rye, and the Heart of Jewish Delicatessen" (Houghton Mifflin Harcourt) dedicated to saving the Jewish deli from extinction, mayonaise, and various other atrocities that dare interfere with the purity of meat on rye with mustard.
