Prepare rice in boiling salted water according to package instructions. Wash the thyme, dab dry and put 4 stems aside. Pluck the remaining leaves from the stems and chop them coarsely. Wash lemon, grate dry and cut 4 thin slices from the middle. Wash salmon fillet, dab dry and cut into 4 pieces. Squeeze 1/2 lemon and sprinkle the salmon with it.
Heat the oil in a coated pan. Fry the salmon on both sides for 4-5 minutes until golden brown. Add the lemon slices to the pan 1-2 minutes later and fry as well. Drain rice and stir in thyme leaves. Arrange the salmon on the rice and garnish with lemon and thyme
