Herb Mesa went from a pudgy kid to a rock-hard personal chef and trainer. Known as "the energy chef," The Next Food Network Star finalist won viewers with his sentimental childhood stories and nutritious take on fat-laden favorites. We asked the father of two for a school lunch recipe that would keep kids on a good track and he offered up his Healthy Cuban Sandwich. This alternative to the traditional version cuts calories while saving the favored Caribbean flavors. Pack this up in your youngster's lunch pail.
