Some of you became familiar with chef Nate Appleman during his intense stint on The Next Iron Chef. Appleman was known for his nose-to-tail style of cooking, not to mention being ultra competitive. Quite a bit has changed since then. He's now eating on vegetarian burrito from Chipotle every day (he's serious) and working the line at the chain's Manhattan test kitchen. "Chipotle is the first restaurant I've worked in since I started at 14 that doesn't have a freezer."
