Heat olive oil in a large pot or Dutch oven over medium-high heat.
Add the sliced andouille sausage and cook until lightly browned on both sides. Remove from pot and set aside on a plate.
In the same pot, add the onion, bell peppers, and garlic. Cook for about 5 minutes until softened.
Pour in the can of diced tomatoes with green chilies and stir to combine.
Add the chicken or vegetable broth and bring to a boil.
Stir in the rice and Cajun seasoning. Return the sausage to the pot and mix well.
Reduce heat to low, cover, and simmer for 20 minutes.
After 20 minutes, add the shrimp to the pot and stir. Cover and cook for an additional 10-15 minutes, until the shrimp is fully cooked and the rice is tender.
Season with salt and pepper, to taste.
Garnish with fresh chopped parsley before serving.
Serve hot and enjoy!
