Pan fry (or grill) chicken breasts on each side until brown, about 5 min each side.
Preheat oven to 170 degrees.
Place chicken breast on a baking tray lined with baking paper, spread each chicken breast with sweet chili sauce, then sprinkle with chopped macadamia nuts.
Bake in oven for approx 20-30 mins until the juices run clear from the chicken breast (watch the nuts don't burn).
