Preheat oven to 350 degrees F. In a large mixing bowl beat butter with an electric mixer on medium to high speed for 30 seconds. Add sugar and salt. Beat until combined, scraping sides of bowl occasionally. Beat in egg and vanilla until combined. Beat in as much flour as you can with the mixer. Stir in any remaining flour with a wooden spoon. Stir in orange peel, chocolate pieces, and candied fruits and peels.

Shape dough into 1-1/2-inch balls. Roll balls in crushed potato chips. Place balls 2 inches apart on an ungreased cookie sheet. Using the bottom of a glass, flatten balls until they are about 21/2 inches in diameter.

Bake in the preheated oven about 14 to 16 minutes or until golden. Transfer cookies to a wire rack and let cool. Makes 18 cookies.

Place cookies in layers separated by waxed paper in an airtight container; cover. Store at room temperature for up to 3 days or freeze for up to 3 months.
