In the late 1980s, I think 1988, McDonald ran this Fiesta promotion. During the promotion, they gave some of their food, McNuggets specifically, a south of the border twist. To make it a little more “festive” they even included a coin collecting gimmick. So every time you bought some Fiesta Nuggets, with its special sauce selection you received a real Latin American coin. I remember very fondly trying to get my hands on all 6 of the coins they offered so that I could fill up my little card.
I have been trying to figure out which sauces were available with the Fiesta, but I cannot find a source that tells me. I was addicted to the Sweet and Sour even back then and while I liked the coins, I could not bring myself to enjoy a new sauce. In this commercial you get a brief glimpse of what could be the sauces:
If you wanted to wash down all that delicious McNuggets goodness, might I suggest the sorely missed, Fiesta Colada Shake?
