Beat together the egg whites, vanilla, and salt until frothy with an electric mixer. Slowly beat in the sugar, 1 tabls. At a time, on medium. Continue beating meringue until sugar dissolves and whites get glossy and form soft peaks. Gently fold in the choc chips and nuts. Drop by teaspoonfuls on well-greased cookie sheet. Place in the preheated oven. Close the door and turn the oven off. Do not open the oven door for 4-5 hours (best to leave overnight).
