Heat the olive oil in a large skillet over medium heat. Add the chopped onions, bell pepper, and celery. Sauté for about 5 minutes until the vegetables are tender.
Stir in the minced garlic and cook for an additional minute until fragrant.
Add the ground chicken (or turkey) to the skillet, breaking it apart with a spoon. Cook until browned, about 5-7 minutes.
Sprinkle the Cajun seasoning, smoked paprika, cayenne pepper, salt, and pepper over the meat mixture. Stir thoroughly to coat.
Add the rice to the skillet and stir, letting it toast for about 2 minutes.
Pour in the chicken broth and diced tomatoes. Bring to a simmer, then cover and reduce the heat to low.
Cook for about 20 minutes, or until the rice is tender and has absorbed the liquid, stirring occasionally to prevent sticking.
Once the rice is cooked, fold in the frozen peas and let it sit covered for an additional 5 minutes.
Fluff the rice with a fork, adjusting the seasoning if necessary.
Garnish with chopped green onions and fresh parsley before serving.
Notes
Adjust the cayenne pepper for desired spice level.
