Salt and pepper the salmon fillets after patting them fully dry.
Heat up the olive oil on a pan on medium to medium high heat.
Depending on the size of your pan, you may need more oil. You'll want to make sure there is a solid thin layer of oil on the pan or your salmon will shred.
Sear the salmon for 4 - 5 minutes on the bottom side of the salmon, move the salmon every now and then so it doesn't stick.
Sear the top of the salmon for 1 - 2 minutes. Sear each side for 1 - 2 minutes.
Put the salmon aside on a different plate.
Top off the oil on the pan if you need some and sautee the garlic on a medium low heat.
Add the milk, dried oregano, dried basil, crushed red pepper, ½ tsp salt, crack of black pepper, and parsley.
Whisk in ½ Tbsp of flour thoroughly. Once fully incorporated, whisk in the other ½ Tbsp.
Whisk constantly and turn the heat up to medium to allow the mixture to bubble a thicken.
Add the grated parmesan and continue to whisk.
Toss in the spinach, the water from the spinach will make sure the sauce doesn't thicken too much. Stir.
Place the salmon back in the pan and spoon the sauce over the fillets.
Sprinkle in the sundried tomatoes cover with a lid for a few minutes.
Enjoy alone or with some pasta!
