In a container or a Ziploc bag, marinate the salmon fillets and miso marinade in the fridge overnight.
Turn on the broiler in the oven.
Remove excessive miso marinade from the fillets. Line the cooking sheet with aluminum foil and place the salmon fillets skin-side down.
In the middle rack, broil for 10-12 minutes, until cooked.
Remove the salmon from the foil and plate skin-side down.
Garnish with lime juice, a slice of lime, and parsley on top. Enjoy!
