In a non-metallic mixing bowl, whisk together 3 tablespoons extra virgin olive oil, 1/2 teaspoon black pepper, 1 tablespoon chopped fresh dill, and 1 tablespoon chopped fresh oregano.
Add the zest and juice of 1 lemon to the oil and herb mixture and stir to combine.
Place 4 salmon fillets into the marinade and turn to coat each fillet; cover and refrigerate for at least 30 minutes and up to 3 hours.
When ready to cook, heat a heavy frying pan or skillet over medium-high heat until hot.
Season the marinated salmon fillets with 1/2 teaspoon salt.
Place the salmon presentation side down in the hot pan and cook undisturbed for 3 minutes.
Carefully flip the fillets and cook for an additional 3 minutes, or until cooked to your desired doneness.
