Combine the salsa ingredients in a bowl and allow the flavours to combine by allowing it to sit for a couple of hours.
Preheat the oven to 180 degrees Celsius.
Brush the chicken with olive oil and seasoning. Heat a grill pan or barbeque to hot then add the chicken to sear on one side for a two minutes. Turn the chicken and sear it on the other side for another two minutes. Place the chicken on a baking tray and place it in the oven to cook through for between 8 - 10 minutes.
Serve the chicken with the salsa on the top with an accompanying green salad.
