Pat the salmon filets dry and season them on all sides with salt, pepper and garlic powder.
In a large skillet, heat the butter and olive oil over medium high heat and add the salmon filets. Sear the filets on both sides for about 3 minutes. Set them aside and keep them warm under a tin foil tent.
In the same skillet over medium heat, (add 1 tbs more of olive oil if needed) add the chopped sun dried tomatoes and garlic. Stir them into the oil for about 2 minutes.
Slowly pour in the vegetable broth and heavy cream. Season the sauce with salt, pepper and Italian seasoning.
Reduce the heat to low and let the sauce simmer for about 3-5 minutes or until it begins to thicken.
Stir in the spinach for about 2-3 minutes or until it wilts into the sauce ans stir in the Parmesan cheese.
Finally, add the salmon back into the skillet and spoon the sauce over the filets. Serve warm and enjoy!
