Add garlic to pan- Let cook until fragrant- 1-2 minutes.
Add Heavy Whipping Cream, Parmesan cheese, Pepper, and Red pepper (if using).
Bring to a boil and whisk occasionally until the sauce is thickened.
Add Chopped Spinach, stir in, and cook until all spinach is wilted.
Move Salmon back to skillet and spoon sauce over.

Notes
If your sauce looks too thick, add a splash of more heavy whipping cream. If it doesn’t look thick enough, continue to heat and whisk. It will thicken.This is a quick cooking process. If you need to keep it warm while you wait for your side to be ready, you can just put lid on It and remove from heat.
