Stir fry the mushrooms in the wok. Stir fry the broccoli in the wok. Combine the chicken, mushrooms, broccoli, bamboo shoots, and cashew nuts in the wok. Stir fry to get everything warm again. Add the bouillon-cornstarch sauce and stir until thickened.
Notes Serve with rice.
Don't forget to start the rice so that it will be done at the same time as the chicken. Bamboo shoots are available in cans at Chinese grocery stores. Fresh broccoli is preferable to frozen, and it should be stir-fried for only a few minutes to keep it crunchy. Endless variations of this basic recipe are possible. Beef, pork, or other lean meats can be substituted for the chicken.
