Sauteed Pork, Taro and Korean Mushrooms

This is another example of cooking without a recipe...

1 small thumb of ginger, sliced thinly
1 small onion, sliced thinly
1 piece of pork tenderloin, cleaned, trimmed and sliced into matchstick strips
1 piece of taro, cubed or sliced in strips
1 pack of Korean shimeji mushrooms
2 pieces Korean King Mushrooms, sliced
light soy sauce
oyster sauce
salt and pepper, to taste

Marinate the pork strips in soy sauce and oyster sauce (a 350-gram piece with 2 tablespoons soy sauce and 1 tablespoon oyster sauce, as well as ground black pepper) for about 15 minutes.

Meanwhile, fry the taro pieces until almost cooked and lightly browned.  Set aside to cool slightly.

Saute the ginger and onions.  Add the marinated pork and cook until half done.  Throw in the mushrooms.  Add chicken stock, 1/4 cup at a time, so the mixture is not too dry.  Finally, add the taro.  Season to taste.  Simmer until done; thicken with cornstarch slurry.

Done!
