Ingredients

1 side of salmon (about 2 1/2 pounds; preferably wild), skinned

1 tablespoon extra-virgin olive oil

Coarse salt and freshly ground pepper

1/4 cup diced radish

1/2 cup diced, peeled English cucumber

1 tablespoon prepared horseradish

3 tablespoons thinly sliced scallions (about 2)

Preparation

Preheat oven to 425 degrees. Place salmon on a parchment-lined baking sheet, and drizzle with 2 teaspoons oil. Season with salt and pepper. Roast salmon until just cooked through (it will be opaque around edges), 8 to 10 minutes.

Meanwhile, stir together radish, cucumber, horseradish, scallions, and remaining teaspoon oil until combined. Season with salt and pepper. Serve with salmon.
