Preheat oven to 350 degrees or heat grill. Season salmon fillets with salt and pepper, drizzle baking pan with 1 tablespoon olive oil, then place salmon fillets, skin side down in baking dish. Bake 12-15 minutes until desired doneness. If grilling, oil grill grate and grill about 10 minutes, skin side down until desired doneness.
In a shallow bowl, ladle one to two scoops of the sauce and place a salmon fillet on top. Garnish with fresh oregano leaves and serve immediately. Store any excess sauce in the fridge for up to a week.
