This herby exotic tasting marinade gives chicken and fish a really super flavor. It can also transform tofu to a spicy and savory meal. Make this Lemon Cilantro Marinade ahead of time. And either... store it in a jar in the fridge where it will last for up to 3 days, or bag and freeze it to use indefinitely. Although the herbs may lose their bright color in the freezer, the flavor will still be there and will even intensify.
