In a large skillet, heat the olive oil over medium-high heat. Add the chicken pieces and sausage slices, cooking until browned, about 5-7 minutes. Remove from the skillet and set aside.
In the same skillet, add the onion and bell pepper. Sauté for about 3-4 minutes until softened. Stir in the garlic and cook for an additional 1 minute.
Add the rice to the skillet, stirring to coat it with the oil and vegetables. Cook for 2 minutes until the rice is slightly toasted.
Pour in the diced tomatoes (with their juice), chicken broth, Cajun seasoning, paprika, salt, and black pepper. Stir well to combine.
Bring the mixture to a boil, then reduce the heat to low. Cover and simmer for 15 minutes.
After 15 minutes, add the cooked chicken and sausage back to the skillet, along with the frozen peas. Stir to combine, cover, and cook for an additional 5-7 minutes, or until the rice is tender and the liquid is absorbed.
Remove from heat and let it sit for 5 minutes before serving. Garnish with sliced green onions.
