Preheat oven to 350 degrees F (175 degrees C). Line your cookie pans with parchment paper. And, you can reuse it (like make 2 pans of cookies on one p. paper sheet). DO NOT NOT use parchment paper! You'll be sorry.
In a large bowl, cream together the butter, applesauce, brown sugar and white sugar until light and fluffy. Add the eggs one at a time, beating well with each addition, then stir in the vanilla. Combine the flour, salt, and baking soda, then gradually stir into the creamed mixture. Finally, stir in the oats, raisins, nuts and chocolate chips. Drop by rounded spoonfuls onto the prepared cookie sheet.
Bake for 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.
