Coat a 13" X 9" baking pan with non-stick spray and set aside. In a food processor, mix the egg, egg white, sugar and brown sugar until smooth. Add the oil and vanilla; process for 10 to 15 seconds. Add the flour, baking soda and salt. Process until the mixture until it is just blended. Add the oats and incorporate with on/off turns. Sprinkle with the raisins and use a fork to lightly mix them in. Transfer the dough to the prepared pan. Wet your fingers with water and press the dough evenly into the pan. Bake at 350 degrees F for 25 to 30 minutes, or until a toothpick inserted in the center comes out clean. Cool in the pan.
