01 - Preheat the oven to 400°F. Prepare a baking sheet by lining it with parchment paper or lightly oiling.
02 - Arrange salmon fillets on the prepared sheet. Drizzle with olive oil, season with sea salt and black pepper, then top each fillet with a lemon slice.
03 - Bake the salmon for 12 to 15 minutes until just cooked through and flaky, adjusting time based on thickness.
04 - While salmon bakes, combine pomegranate seeds, walnuts, parsley, red onion, olive oil, lemon juice, pomegranate molasses (if using), salt, and pepper in a medium bowl. Toss gently to blend.
05 - Remove salmon from the oven and allow to rest for 2 minutes.
06 - Spoon the pomegranate walnut salsa generously over each salmon fillet and serve immediately.
