Season the salmon fillets with salt, pepper, and garlic powder or Italian seasoning. Heat a large skillet over medium-high heat and add the olive oil. When the oil is hot, place the salmon fillets in the pan and sear for 2 minutes on each side. Remove the salmon from the pan and set aside.
In the same skillet, melt the butter over medium heat. Add the minced garlic and shallot and cook for 1 to 2 minutes, until fragrant. Add the white wine to deglaze the pan, scraping up any browned bits.
Pour in the chicken broth and bring to a simmer.
Stir in the orzo pasta and cook for 10 minutes, stirring occasionally, until tender and the broth is absorbed.
Once the orzo is done, stir in the heavy cream, grated parmesan cheese, and a squeeze of fresh lemon juice.
Add the seared salmon fillets back into the skillet. Add the rinsed spinach leaves and let everything cook together for 2 to 3 minutes.
Serve and garnish with chopped parsley.
