Heat oven to 375 degrees. Grease cookie sheets. In large bowl, combine sugar, brown sugar, oil, vanilla, egg whites, pudding mix and sour cream at low speed until moistened; beat 2 minutes at medium speed. Add flour, rolled oats, baking soda and salt; mix at low speed until blended.
Blend in pecans and chocolate chips.
(Tip: If dough is too soft, cover with plastic wrap and refrigerate about 1 hour, or stir in an additional 1/4 cup flour for easier handling.)
Drop by rounded tablespoonfuls 2 inches apart onto greased cookie sheets.
Bake at 375 degrees for 6 to 7 minutes or until set. Do not overbake. Cool 1 minute; remove from cookie sheets.
