Heat the olive oil in a large skillet over medium heat. Add the sliced sausage and cook until browned, about 5 minutes. Remove and set aside.
In the same skillet, add the diced onion, red bell pepper, and green bell pepper. Sauté for about 3-4 minutes until the vegetables soften.
Add the minced garlic and cook for an additional 1 minute until fragrant.
Stir in the rice and cook for 1-2 minutes, allowing the rice to absorb the flavors.
Pour in the chicken broth and diced tomatoes. Add the Cajun seasoning, smoked paprika, salt, and pepper. Stir well to combine.
Bring the mixture to a boil, then reduce the heat and cover. Let it simmer for about 15 minutes or until the rice is cooked and has absorbed most of the liquid.
Add the browned sausage back into the skillet, stirring to combine. Cook for an additional 2-3 minutes until heated through.
Remove from heat and garnish with sliced green onions and chopped parsley before serving.
