Dice chicken, place in a bowl and mix with marinade ingredients. Before dicing bamboo shoots, blanch in boiling water for 30 seconds (to remove tinny, canned flavour). Mix all the sauce ingredients in a small bowl. Heat wok, add 2 tablespoons vegetable oil an stirfry pine nuts until golden brown. Set aside on paper towel. Using the same wok, heat again and add 2 tablespoons vegetable oil. On high heat, add garlic and stir-fry 10 seconds, then add chicken with marinade and stir-fry until white, but not completely cooked through. Add sauce and bamboo shoots and cook for 2 minutes. Add pine nuts and green onions, mix well and serve.
