Pour cilantro mixture over the fillets, and turn to coat. Marinate in the refrigerator 30 minutes, turning once.

Inspired by the popular cocktail, sweet, delicate grouper takes on a tangy flavor from the fresh lime juice and tequila. Pair the grouper with yellow rice, black beans, and a pitcher of margaritas, of course.
