I agree with the other poster: fry the rice. Medium High heat to the color according to your liking. My mom always told me that the secret to most cooking is the quality of the broth used. There are common denominators to all dirty rice: onions, garlic, liver, ground pork, ground beef, bell pepper, rice. But I believe that your broth will determine the level of the dishs' quality. Make chicken soup and use that broth. lots of chicken legs and thighs. and water to cover,... boil, skim, and cool down... Cooling down is critical for absorption of your veggies used on your soup,.. to the chicken.
The rest,... is perfunctory. Google any recipe of dirty rice... and follow instructions.
And by the way,... cooking is about "giving"... make it for someone you love,.. and it'll come out great !
sincerely,
