Prep the oven and pan. Preheat the oven to 325°F. Grease baking sheets or line with parchment paper.

Melt the chocolate chips. Melt the chocolate chips in a bowl over simmering water or in the microwave oven. Set aside to cool.

Make the batter. In a mixing bowl using an electric mixer, beat the egg whites until foamy; beat in the salt. Gradually beat in the sugar and continue beating on high speed until very thick and the mixture holds stiff peaks. Fold in the vanilla and the cooled melted chocolate. Fold in nuts.

Bake the cookies. Use a tablespoon or scoop to drop the mixture onto the prepared baking sheets. Bake for 9 or 10 minutes, or until firm and set but still soft.
