Heat olive oil over medium-high heat in a large ovenproof skillet. Add chicken and cook each side for 4 minutes or until cooked. Set aside.
Add onion and garlic to the pan and cook for 2 minutes until starting to soften. Add capsicum and cook for a further 2 minutes.
Add remaining ingredients except rice and cheese. Bring mixture to a simmer.
Add rice to pan. Stir, and turn heat down to medium-low. Cover and cook until rice is tender and most of the liquid is absorbed – about 15-20 minutes. Do not stir while it cooks.
Meanwhile, roughly chop chicken. When rice is cooked, quickly stir through chicken. Sprinkle with cheese and put under the grill until golden and bubbly.
Serve garnished with fresh coriander.
