How to Make It
Heat the oil in a large, deep skillet. Add the mustard seeds and cook over high heat until they pop, about 1 minute. Add the curry leaves and crushed red pepper and cook until the leaves sizzle, about 30 seconds. Add the cabbage, carrots, beans, onion, coconut, green chiles and turmeric and cook over moderately high heat, stirring, until the vegetables start to soften, about 3 minutes. Continue cooking over moderate heat, stirring occasionally, until the vegetables are crisp-tender, about 5 minutes longer. Season with salt and serve.
