1 1/4 cups reduced fat margarine
1/2 cup white sugar
3/4 cup packed brown sugar
2 egg whites
1 teaspoon vanilla extract
1/2 cup all-purpose flour
1 teaspoon baking soda
3 cups rolled oats
Preheat the oven to 375 degrees F (190 degrees C).
In a large bowl, cream together the margarine, white sugar and brown sugar until smooth. Beat in the egg whites one at a time, then stir in the vanilla. Combine the flour and baking soda; stir into the sugar mixture. Mix in the rolled oats. Drop dough by teaspoonfuls onto ungreased cookie sheets.
Bake for 8 to 10 minutes in the preheated oven. Allow cookies to cool on baking sheet for 5 minutes before removing to a wire rack to cool completely.
