Preheat oven to 350 degrees Fahrenheit.

Brush one side of salmon fillets with one teaspoon olive oil. Spread black pepper on a plate.

Place remaining three teaspoons olive oil into a small bowl. Add capers, lemon zest, lemon juice and salt, and mix well.

Press salmon fillet, oiled-side down, into black pepper. Place onto baking sheet, peppered-side up. Repeat process with the other fillets.

Spread caper mixture over salmon. Cook for 20 minutes, or until fish flakes easily.

Garnish with fresh lemon and serve with salad, rice or pasta. Salmon tastes great served fresh out of the oven or at room temperature.
