Heat olive oil in a large frying pan and cook chicken breasts for 6-8 minutes. Place in a bowl and set aside.
In the same pan, cook onions for 3-4 minutes until translucent. Add red pepper, garlic, chorizo, shrimp, and cajun seasoning. Cook for another 5 minutes.
Add the chicken back in along with Worcestershire sauce, salt, and black pepper. Stir in and add rice, tomatoes, and chicken stock. Bring to a boil, reduce heat, cover and simmer for about 25 minutes or until the rice is completely cooked and liquid is absorbed. Enjoy!
