How to Make It
In a large, deep skillet, heat the oil. Add the onions and chiles and cook over moderately high heat, stirring, for 2 minutes. Stir in the curry leaves, pepper and turmeric. Reduce the heat to moderate. Add the green beans and cook, stirring occasionally, until the onion is translucent, about 4 minutes. Cover and cook, stirring occasionally, until the beans are tender, about 6 minutes longer. Season with salt and serve.
