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, finely chop rosemary and coarsley chop macadamias. 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 baby spinach / salad / greens on the side. Spoon over salsa.
