Heat oven to 350°F. In large bowl, beat butter, sugars, vanilla and eggs with electric mixer on medium speed, or mix well with spoon until well blended. Lightly spoon flour into measuring cup; level off. Stir in flour, baking soda and salt. Using heavy-duty wooden spoon, stir in chips and pecans; dough will be stiff and chunky (you may need to use your hands).
