Key Lime Fudge

3 cups white baking pieces
1 (14 ounce) can sweetened condensed milk
2 teaspoons finely shredded lime peel

1 cup chopped macadamia nuts, toasted, if desired

In a large heavy saucepan cook and stir baking pieces and sweetened condensed milk over low heat just until pieces are melted and mixture is smooth. Remove from heat. Stir in lime peel and lime juice. Stir in nuts.

Spread mixture evenly in prepared pan. Cover and chill about 2 hours or until set.
