Liver a la Chinese (recipe)

Ingredients
- Organic beef Liver
- onion (chopped)
- pinch of salt
- oregano
- pinch of pepper
- vinegar (2 tbsp)
- soy sauce (1 tsp)
- frying oil
- two tablespoons of flour

Chop the liver into pieces on a wooden block using the chopper (wide
blade). Combine all the ingredients into a bowl. Heat the oil. Then
put in the mix and fry for five minutes covered, then turn over the pieces
and fry for another five minutes. Cut a piece in half to see if it
is cooked. It is cooked if there is no blood. Don't fry for too long
because the liver will get hard.
