Wash chicken and remove skin from meat. Pierce breasts several times with a fork and set aside.

Grate the lime peel, using medium sized grater slots. (Grate only the green part of the lime's peel). Sprinkle the grated peel over the breasts. Place chicken in a larger bowl, and pour the mixture of tequila and margarita mix over the chicken; slice and squeeze the lime over the meat, and place lime slices in the bowl. Allow to marinate at least one hour.

Remove chicken from marinade, pat dry, and grill over medium heat, until the chicken is done. Discard marinade prior to grilling. Baste chicken with fresh tequila and mix if desired.

(Basted it right out of the bottle...heh...heh... basted myself as well).
