Beat cream cheese and sugar in large bowl with electric mixer on medium speed until well blended. Gradually add food colouring until cream cheese mixture is of desired colour. Blend in mint extract. Add eggs, 1 at a time, beating on low speed after each addition just until blended. Pour half of the batter over crust. Remove 16 of the cookie quarters; set aside for garnish. Spread remaining cookie quarters evenly over batter in pan; cover with the remaining batter.
