If you're using an oven burner to grill, lightly oil a pan and preheat it to low-medium/medium.
Melt the coconut oil for 15 to 30 seconds in the microwave (until fully liquid).
Mix the oil, the Old Bay seasoning, the garlic powder, and the pepper together. Stir until fully combined.
Glaze the tops of the salmon filets with the Old Bay oil mix.
Place the salmon filets (skin-side down) directly on the grill or grilling pan.
Grill for 6 to 8 minutes, or until the meat is pink and flaky in the thickest part of the filet.
