In a large bowl, cream together the shortening, butter, white sugar, and brown sugar until smooth. Beat in the eggs one at a time, then stir in the vanilla. Combine the flour, baking soda, and salt; stir into the creamed mixture. Stir in the pecans and chocolate chips. Use a measuring tablespoon to round dough into balls. Don't roll the balls, just make them rounded. Place onto ungreased baking sheets.
Bake 10 to 12 minutes in the preheated oven, or until centers are set and very lightly browned. Don't overbake. Cool 2 to 3 minutes before removing from baking sheets. Make sure you have lots of ice cold milk!!!
