Fennel and Apple Slaw:
Place the stock, ginger and garlic in a deep frying pan over medium heat and bring to a simmer. Add the chicken and cook for 5 minutes each side. Remove the pan from the heat and allow the chicken to stand for 10 minutes. Remove the chicken from the stock, shred and toss with the sesame seeds and salt.
To make the fennel and apple slaw, combine the fennel, apple and mint. Divide between serving plates and top with the shredded chicken. Combine the buttermilk and lemon juice and spoon over the salad to serve.

Richard Wrangham, a professor at Harvard University and author of Catching Fire, studies the role of cooking in human evolution. "Once you start thinking about the importance of cooking -- its supply of energy, its strange distribution compared to natural foods -- it's bound to have affected our evolution hugely, our behavior, our society, our cognition, all sorts of features about us," he says.
