Preheat the oven to 350 degrees F.
In a large bowl, with the mixer on medium-low speed, beat the sugars and vegetable spread until well blended, occasionally scraping the bowl with a rubber spatula. Add the egg, egg white and vanilla, and beat until smooth. Beat in the flour, baking soda and salt until mixed.
With a wooden spoon, stir in the oats and chocolate chips until well combined. Drop the dough by rounded measuring tablespoonfuls 2 inches apart on ungreased large cookie sheets. Bake until golden, 12 to 13 minutes. Bake in batches if needed. With a wide, metal spatula, transfer the cookies to a wire rack to cool.
