PREPARATION:

1. Remove dough from wrapper. Divide dough into thirds.
2. Combine 1/3 of dough, 1/8 teaspoon peppermint extract and enough red food coloring to make dough desired shade of red or pink. Knead dough until evenly tinted.
3. Repeat with second 1/3 of dough, remaining 1/8 teaspoon peppermint extract and green food coloring.
4. To assemble, shape each portion of dough into 8-inch log. Place red log beside green log; press together slightly. Place plain log on top. Press logs together to form one tri-colored log; wrap in plastic wrap. Refrigerate 2 hours or overnight.
5. Preheat oven to 350°F.
6. Cut log into 1/4-inch-thick slices. Place 2 inches apart on ungreased cookie sheets. Bake 8 to 9 minutes or until set but not browned. Cool 1 minute on cookie sheets. Remove to wire racks to cool completely.
