Preheat oven to 350 degrees.
Beat egg whites until foamy, approximately 3 minutes.
Slowly add sugar while beating egg whites until stiff.
Stir in salt, vanilla, pecans and chocolate chips.
Drop onto ungreased cookie sheet by the spoonful (I used a small dining spoon so the cookies were about 1 tablespoon of the batter each).
Turn off the oven. Place cookies in the oven and leave until morning without opening the oven while they are hardening.
