Whisk together 1/4 cup of extra virgin olive oil, 2 tablespoons of freshly squeezed lemon juice, 2 cloves of minced garlic, 1 teaspoon each of dried oregano and thyme, along with salt and black pepper to taste.
Place the 4 salmon fillets in a shallow dish and pour the marinade over them, ensuring each fillet is well-coated, and let marinate for at least 15 minutes.
Preheat your grill to medium-high heat.
Carefully remove the salmon from the marinade and discard the leftover marinade.
Place the salmon fillets skin-side down on the grill and cook for about 5-6 minutes until they develop a lovely golden-brown color, then gently flip and cook for another 4-5 minutes or until they flake easily with a fork.
Remove the salmon from the grill and allow it to rest for a couple of minutes. Serve with fresh lemon slices and garnish with chopped parsley.
