Stir Fry Beef and Mushroom

I had a package of mushroom in our fridge that I wouldn't want to just go to waste so I decided to cook the beef with the mushroom.

Ingredients:

Beef (sliced thinly)

Mushroom (quartered)

Carrots (cut diagonally, thin sliced)

ginger (sliced in small strips)

olive oil

For Marinade:
dry sherry

soy sauce

cornstarch

pepper

garlic powder

For sauce:
water

oyster sauce

Directions:

Marinade the beef for at least 15 minutes. Mix water and oyster sauce and set aside. Sautee ginger until aromatic. Add marinated beef and brown for few minutes. Add oyster sauce and water mixture. Bring to boil. Add carrots and mushroom. Cook until sauce becomes thick. Serve over hot rice.
