Preparation Tips: Tofu, also know as soybean curd, is available in health-food stores, Asian markets and many supermarkets. It is very perishable and should be refrigerated for no more than 1 week. Tofu should be stored covered with water, which should be changed daily. It can also be frozen for up to 32 months. Freezing will change its texture, making it slightly chewier. If you prefer, you may substitute diced cooked chicken breast for the tofu.
