In a large skillet, heat the olive oil over medium heat. Season the salmon fillets with salt and pepper, then add them to the skillet. Cook for about 4-5 minutes on each side, or until cooked through. Remove the salmon from the skillet and set aside.
In the same skillet, add the shrimp and cook for 2-3 minutes until they turn pink. Remove the shrimp and set aside with the salmon.
In the skillet, add the minced garlic and sauté for about 30 seconds until fragrant.
Pour in the heavy cream and stir well. Add the lemon juice, dried parsley, salt, and pepper. Let the sauce simmer for 3-4 minutes until it thickens slightly.
Return the salmon and shrimp to the skillet, gently coating them with the creamy sauce. Cook for an additional 2 minutes to heat through.
Serve immediately, garnished with fresh parsley.
