Over moderate heat, fry the onion in oil until lightly browned, stirring to prevent scorching.
Add the tomatoes, salt and curry powder and continue stirring for 2 to 3 minutes. Add the cabbage, carrots and pepper, and mix well.
Then pour in about half a cup of water. Cover the pot, reduce the heat, and
simmer until the liquid is absorbed and the cabbage is still slightly
crunchy.
