Add olive oil to a large skillet over medium heat. Once hot, add cubed chicken.
Cook for about 5-7 minutes, stirring occasionally, until chicken is just cooked through.
Stir chicken stock, rice, and parsley into the skillet.
Bring to a boil and then reduce the heat to low. Cover skillet and simmer for 15-20 minutes, until rice is cooked and tender.
Stir in chopped carrots and peas until warmed through.
