Beat together shortening, butter, or margarine (do not use all light margarine), along with sugars, egg, applesauce or water, and vanilla extract, until creamy.
Mix together flour, salt, and baking soda. Make sure that it is well mixed. Add oatmeal to this dry mixture; mix well. Add dry mixture to wet mixture, about 2 cups at a time. Alternate with adding dried cranberries, nuts & seeds. Stir well, after each addition.
Drop by rounded teaspoonfuls onto greased cookie sheets. Bake 12 to 15 minutes. Remove cookies from pans & place on cooling racks.
