Pat the chicken dry and rub with olive oil.
Coat both sides evenly with Cajun seasoning.
Heat a large skillet over medium heat and melt the butter.
Stir the honey into the melted butter until combined.
Add the chicken and sear for 1–2 minutes per side until lightly browned.
Remove the chicken and place it on a plate.
If needed, add another tablespoon of butter.
Add celery, bell pepper, and garlic to the skillet and sauté for about 1 minute.
Stir in the uncooked rice, Cajun seasoning, and chicken broth.
Bring everything to a gentle boil.
Reduce the heat to medium-low and return the chicken to the skillet, placing it over the rice.
Cover and cook for 15–20 minutes, or until the Cajun Chicken & Rice Skillet is fully cooked and the rice is tender.
Remove from the heat and let stand for 5 minutes.
Fluff the rice with a fork.
Serve with diced mango, chopped cilantro, and fresh lime wedges.
