Green Beans in Mustard Seeds

This recipe was given to me by chef extra-ordinaire Ramu in India during our visit there. It's really super easy.
Ingredients:
3 cups green beans
2 tablespoons olive oil
1 teaspoon mustard seeds
salt to taste

Method:

1. Wash and trim the ends of the green beans.
2. Heat a pan on medium heat and add the olive oil. When the oil is warm (about 30 seconds) add the mustard seeds. Cook the mustard seeds until they start to "jump".
3. Add the beans and stir so beans are coated in the seeds. Cook at Medium High for 2-3 minutes.
4. Cover and cook at low for 5 -6 minutes.
5. Can be served hot or cold.
