1. Preheat oven to 300º.
2. Salt and pepper both sides of salmon and place in a baking dish. Top with sliced lemons and oranges that have been sliced very thin. ( I used a mandolin). Place fresh herbs on the top and around the salmon. Pour olive oil over the salmon so that it is resting in a pool of olive oil. The amount will depend on the size of your fish and baking dish. Sprinkle red pepper flakes over the salmon and also in the olive oil on the sides.
3. Bake for 20-25 minutes depending on the thickness of the fillet. It should start turning opaque around the edges.
Add just enough olive oil to cover the surface of the pan, it does not need to cover the fish.
