Set in a shallow pool of briny, gingery oil, mild fish fillets cook effortlessly on a sheet pan, layered with bold lemon, olives and capers, similar to a deconstructed tapenade. The mixture is brightened even further with the addition of grated ginger, which provides a zingy contrast to the salty, meaty olives. (But this recipe is flexible: Sliced garlic or anchovies would also work nicely, taking a more savory turn.) Nestling the delicate fish in oil helps it stay moist in the oven, and creates a no-effort pan sauce that is best served with bread, to soak up every delicious drop.
