1Heat the oven to 375º. Crack the egg on side of the bowl, letting egg slip into bowl. Add the granulated sugar, brown sugar and margarine to egg. Stir with the wooden spoon until mixed.
2Add the flour, baking soda and salt to sugar mixture. Stir until mixed.
3Stir the candies into the dough. Drop dough by rounded tablespoonfuls onto the cookie sheet (you do not need to grease the cookie sheet).
