In a sauce pan, mix together the butter, honey, garlic, and soy sauce until combined. Bring it to a simmer and allow it to simmer for up to 2 minutes.
Place the salmon fillets on a big sheet of aluminum foil inside of a baking dish, skin side down. Season the surface of the salmon with a pinch of salt.
Reserve a couple spoonfuls of the sauce before pouring the rest of the sauce all over the salmon fillets, making sure that everything is nicely covered. Brush the top of the salmon fillets with your reserved sauce.
Fold up the foil and place into the oven for 10 minutes. After 10 minutes, open up the salmon and turn on the broiler and let the salmon cook for 3-4 more minutes.
