Heat a medium frying pan on a medium high heat. Season salmon with salt and rub with a little oil. Pan fry for 3-5 minutes on each size or until salmon is cooked to your liking.
While the salmon is cooking mix rosemary, olive oil, macadamias and lemon juice in a small bowl with a pinch of salt. Taste and adjust with more salt and lemon if you think you need it.
To serve divide cooked salmon between 2 plates. Pop spinach / salad / greens on the side. Spoon over salsa.
