Cream together sugars and oil. Add egg and vanilla extract. Mix until smooth, then stir in the salt and baking soda. Mix in the oats, flour, and rice crispies just until mixed. Stir in the nuts and chocolate chips. Pour batter on a cookie tray and spread on the thinner side.

Bake for 20-25 minutes, or until browned. Wait a few minutes to cut. It's okay if it breaks apart. Let cool.
