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 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.
Wrap the chicken in foil to rest for about five minutes and serve with the salsa on the top, some mixed greens and steamed fresh asparagus.
