Heat the oil in a deep pan, add the onions and
fry for a few minutes till lightly browned. Add the red peppers,
stir, then add tomatoes, chilli, salt and pepper. When it starts
boiling, lower the heat to the minimum, cover and simmer for 1/2
hour. Stir once. (if it gets too dry before the end of cooking
add 1/4 cup of water and continue cooking). Take off the heat
and leave covered to stand for 10 minutes or more. Fluff with
a fork and serve hot or cold with salad.
