1. In a Sauté Pan, place the olive oil, diced red onion, minced garlic, and Andouille sausage in the skillet. Cook on medium-high heat for 5 minutes, stirring occasionally.
2. Add in the diced bell pepper and Cajun seasoning. Mix well and cook with the lid on for 5 additional minutes.
3. Once the peppers begin to soften, add in the plum tomatoes, mix well and reduce the heat to medium. Cook for 5 minutes with the lid off. Then add in the shrimp and cook for 5 minutes with the lid on.
4. Divide the rice between 4 plates, then divide the Cajun shrimp and Andouille sausage between the plates. Top each plate with minced fresh parsley, enjoy immediately.
Note: The key to making this quick cooking dinner is cutting all the vegetables and sausage in advance before you begin to cook.
