Marinate the meat in marinade for 4 hrs in the fridge. (Overnight marination is even better)
Heat up your wok / skillet on medium high heat and once heated add some cooking oil. Add the meat and all vegetables (except for the enoki mushrooms) and stir occasionally.
Once the meat and the vegetables are half cooked, reduce the heat to medium and cook further until all ingredients are fully cooked.
Add the enoki mushrooms a few minutes before you serve and quickly stir it. Serve.
