Beat 4 egg whites until foamy: add 1/4 t cream of tartar and 1/4 t salt. Continue beating until stiff; then beat in 1 1/2 c sugar a little at a time.
Fold in 1 8 oz package of semisweet chocolate chips and 1 cup chopped walnuts.
Drop spoonfuls onto parchment paper or brown kraft paper (grocery bags) on cookie sheets.
Bake at 350° F 25 minutes. (Meringues should still be white in color.)
Remove immediately from the paper using a spatula. Makes about 6 dozen.
