Prepare the vegetables by chopping the onion, carrot, celery, sweet red pepper, and green pepper into small pieces. Mince the garlic.

Coat a large nonstick skillet with vegetable cooking spray and heat over medium-high heat.

Add the chopped onion, carrot, celery, sweet red pepper, green pepper, and minced garlic to the skillet.

Sauté the vegetables for 3 to 4 minutes, or until they are tender.

Remove the vegetable mixture from the heat and set aside to keep warm.

In a medium saucepan, combine the water and Cajun seasoning. Stir well.

Bring the water and Cajun seasoning mixture to a boil.

Stir in the uncooked long grain rice.

Cover the saucepan, reduce the heat to low, and simmer for 20 to 25 minutes, or until the rice is tender and the liquid is absorbed.

In a large bowl, combine the cooked rice and the sautéed vegetable mixture.

Add the chopped fresh parsley to the bowl.

Toss gently to combine all the ingredients.

Serve hot.
