Hear that ruckus? It's the sound of sweet carrots and baby lettuces storming the menus at some of the world's best restaurants. Their co-conspirators? Big-deal chefs like Rene Redzepi and April Bloomfield, who are celebrating produce with a reverence formerly reserved for Wagyu beef. They're turning ingredients that used to be side dishes into centerpieces (even if it does involve some pork now and then -- it's not a vegetarian revolution).
