Heat a large, deep, ovenproof skillet over medium high heat and add the oil.
Add the chicken pieces to the pan and sear until browned on both sides. Remove and set aside.
Add the veggies to the pan and cook until softened.
Add the chicken back to the pan and transfer to the oven.
Bake until chicken reaches an internal temperature of 165 degrees.
Remove, and serve the chicken topped with the vegetables.
Use this again: You could chop the leftover chicken and use for a Cajun chicken salad. Or put in a tortilla with some cabbage and sour cream for a Cajun style taco. For one or two servings: Recipe can easily be halved or doubled. Just keep an eye on the temperature, as it may fluctuate. Store leftovers: Leftovers can be stored in the fridge for up to 3 days.
