In a large pan or wok heat oil over medium high heat. Add ginger and garlic. Be careful not to burn, as it will ruin your dish. Stir-fry until fragrant. Add the carrots, celery and shallots. Cook for about 5-8 minutes or until tender. Meanwhile, mix all of the sauces together in a bowl including the sugar. Stir well.
Add the turkey. Stir completely to incorporate all the vegetables. Add the water chestnuts and green onions.
Mix together sauces and sugar and then pour into your turkey/vegetable mixture. Continue stirring so all the flavors combine. Cook until the turkey is cooked through.
