Beef stir fry

150g beef, thinly sliced into bite-size pieces

1 red pepper, sliced

1 onion, sliced

2 cloves garlic, finely chopped

3 dried Shiitake mushrooms

for marinade:

1 Tbsp soy sauce

1 Tbsp Mirin

1 tsp cornflour

1/2 tsp sesame oil   

Soak the mushrooms in some boiling water for 10-15 minutes. Drain and slice. Reserve the mushroom water.

Marinate the beef for 10-15 minutes.

In a large skillet or wok, heat 1 tablespoon of oil over high heat. Add the beef and stir-fry for about 3 minutes. Remove beef and reserve. To the same wok, add and saute the onions, garlic, and mushrooms. Add the peppers. If the mixture seems too dry add some of the mushroom water.  Stir-fry for about 3 minutes and return the beef to the wok. Stirring constantly, add the soy sauce and Mirin.  

Serve with steamed instant white rice.
