Preheat broiler. Spray a large, shallow flameproof baking dish with nonstick spray.
Place fillets in dish. In a bowl, combine butter, lemon juice, salt, pepper, onion powder and nutmeg. Brush fish with sauce, reserving half. Broil 6-inches from heat for 4-6 minutes, just until fish flakes. During last minute or so of cooking, stir roasted almonds into remaining sauce and spread over fish. Sprinkle with fresh chives of choice before serving.
