Add the egg and green food coloring. Beat until combined.
Pour in the flour mixture and mix until well combined.
Fold in the Andes mints and mini chocolate chips, reserving a small amount of candy for topping the cookies if desired.
Use a tablespoon to scoop out the dough and roll it into a ball. Place the balls on the lined cookie sheet, leaving around two inches between each cookie.
Bake then remove from the oven and allow to cool on the cookie sheet for five minutes!
