A new crop of 16 not-so-great cooks, up from 12 in the first season, jumps headfirst into kitchen boot camp with hopes of being crowned the best of the worst at season's end. Chef Anne Burrell, who last season led Rachel Coleman to victory, returns to lead the red team into battle in the show's second season. This time, however, the blue team is led by ``Dinner: Impossible'' host Robert Irvine. Each episode, the contestants face two challenges in the kitchen and the two worst cooks (one on the red team, one on the blue team) are eliminated. The final two cooks are tasked with preparing a three-course, restaurant-quality meal for a panel of three culinary experts. Whoever wins earns a $25,000 prize.
