Heat 2 tablespoons of oil in a saucepan and sauté the onion with the long grain rice. Pour in 300 ml of water, bring to the boil, season with salt and cook covered over a mild heat for 20-25 minutes. The rice should have absorbed all of the water.
In the meantime, clean the zucchini and grate finely. 5 minutes before the rice is cooked, season the two salmon fillets with salt and pepper and fry them in a hot, coated pan with 2 tablespoons of oil and the sprigs of rosemary for 2 - 3 minutes on each side until light brown.
Mix the zucchini with a little cayenne pepper into the hot rice. Arrange with the salmon fillet on plates and serve drizzled with 1 tablespoon of olive oil and 1 squirt of lemon juice.
Note: Fried chicken breast goes well with fresh, juicy rice.
