Heat a large heavy-bottomed
saucepan and cook the salt pork over medium-high heat until
crisp. Add the red and
green peppers,
celery, onion, and garlic and cook 3 to 4 minutes. Add the rice and stir, coating the rice with
drippings. Stir in the
tomatoes,
tomato paste, water, salt, and black and cayenne pepper. Cover and
simmer until the rice is tender and the liquid is absorbed, about 25 to 30 minutes.
