In a small bowl, combine olive oil, Dijon mustard, lemon juice, smoked paprika, garlic powder, salt, and pepper. Pour the marinade over the salmon fillets and let them marinate for about 15 minutes.
In another bowl, drizzle the shrimp with olive oil and season with lemon pepper and smoked paprika. Set aside.
In a skillet over medium heat, add olive oil and butter. Once hot, add the marinated salmon fillets and cook for about 4 minutes on each side until they are golden and crispy. Remove them from the skillet and set aside.
In the same skillet, add the sun-dried tomatoes and sauté for a couple of minutes. Then, add the minced garlic and cook for an additional minute until fragrant.
Stir in the orzo pasta, Better Than Bouillon, and water. Season with herbs de Provence. Bring to a boil, then cover and reduce the heat to a simmer. Cook for about 10 minutes, or until the orzo is tender and the liquid is absorbed.
Once the orzo is cooked, stir in butter, heavy cream, Parmesan cheese, lemon juice, and chopped parsley. Mix until creamy and well combined.
In a separate skillet, heat butter and cook the shrimp for about 4 to 5 minutes, being careful not to overcook.
To serve, place the salmon fillets on top of the creamy orzo and then layer the shrimp over the salmon. Garnish with additional chopped parsley.
