Heat a tablespoon of olive oil in a heavy-based pot over MED-HIGH heat. Add the ground sausage meat and brown it for 5-8 minutes.
Remove the meat. Add the rest of the olive oil to the now-empty pot. Add the onion, garlic, celery, and diced peppers. Sauté for 5 minutes, until the onions are translucent.
Add the meat back into the pot along with the Cajun seasoning, Italian herbs, basmati rice, stock, bay leaves, and salt and pepper. Cover and bring to the boil, then turn down to simmer for 20 minutes or until all the water has cooked away. Turn off the heat and let it steam with the lid on for another 5 minutes.
Remove the lid. Sprinkle on the sliced green onions and parsley and fluff the rice.
