In a large skillet, cook sliced Andouille sausage over medium heat until browned.

Add diced onion, bell pepper, celery, and minced garlic; sauté until vegetables are tender.

Stir in rice, Cajun seasoning, and chicken broth.

Bring to a boil, then reduce heat, cover, and simmer until rice is cooked and liquid is absorbed, about 20 minutes.

Fluff rice with a fork, taste, and adjust seasoning.

Garnish with chopped green onions before serving.
