In a mixing bowl, whisk together olive oil, lemon juice, garlic, oregano, thyme, salt, and black pepper.
Brush the salmon fillets with the lemon herb mixture.
Place the salmon fillets on the grill, skin-side down. Grill for about 6-7 minutes per side, or until the salmon is cooked through and flakes easily with a fork.
Remove from grill and let rest for a few minutes before serving.
