Preheat oven to 375°F. Spray a 9x13-inch glass baking dish with nonstick spray.
Place the salmon fillets in the prepared dish, leaving space between each fillet. Drizzle oil on top of the fillets. Top each fillet with a piece of butter. Sprinkle the salmon generously with salt and pepper. Bake 13 to 16 minutes, or until the salmon is cooked through and flakes apart easily. Cook time will be dependent upon how thick your fillets are.
MAKE THE COCONUT GINGER SAUCE:
While the salmon is baking, in a medium saucepan, mix the sauce ingredients together and bring to a boil. Reduce the heat to low, and simmer (stirring often) until the sauce has thickened slightly. Remove from heat.
Serve the salmon with sauce drizzled on top. Add chives on top, if desired.
Notes
Chili paste can be found in the Asian products section of your market. I use "Sambal Oelek." Ask your grocery manager if you cannot find it!
