Wash and finely mince the cilantro, parsley, and mint. Add the lemon juice, olive oil, and (optional) saffron. Mix together with a fork to combine.
Line a pan with foil and place the fish on top. Season with salt and pepper to taste. Cover with a third of the herb mixture and flip it upside down so the exposed side of the salmon is face down in the sauce. Marinate for 10-15 minutes.
In the meantime, preheat the oven to 375F.
Flip the salmon skin-side down. Cover with a sheet of aluminum foil and bake for 20-45 minutes depending on the thickness of the filet. The internal temperature should be 145°F.
Add another third of the herb mixture half way through cooking.
Serve with the final third of the herb mixture and sabzi polo.

Notes
Do not marinade longer than 15 minutes or the salmon will begin to cook from the acid in the lemon.Do not use more mint than 1 tablespoon or it overpowers the other flavors in the herb mix.
