To make this stuffed salmon, start by preparing the salmon itself. Cut slits or pockets about 3/4 quarter of the way through the salmon, being careful not to cut all the way through. Repeat until each piece of salmon is cut and set them aside.
Next, prepare the filling. Add the softened cream cheese, spinach, mashed garlic, parmesan cheese, and ground black pepper to a bowl and mix to combine. If the cream cheese is not soft, you can microwave it for 20 seconds to soften it.
Then, stuff the filling into the salmon, packing in as much as you can!
In a separate small bowl, mix together the paprika, garlic powder, and cumin until they're fully combined.
Then, rub the spice mixture on top of each piece of salmon.
Once the salmon is seasoned, grease a large, oven-safe skillet (like a 10-inch cast iron) with butter or oil and transfer the salmon pieces into the skillet.
Finally, transfer the skillet into the oven and broil it for 13 minutes, or until the salmon is cooked to your liking.
Once it's done, remove it from the oven, serve, and enjoy!
