Pork with cabbage

In a wide pot with oil covering the bottom, sauté the onion with the leek until they are tender. 

Add the peppers. 

Continue by adding the pork and turn until it gets brown on all sides. 

Slowly add the cabbage to the pot (if it doesn't take it all, put as much as it does, close the lid and wait a while. The steam will make it tended and reduce its volume and then you can add the rest). 

Salt according to taste and leave on medium to low heat to cook until only the oil remains.
