Beat whites to foamy.
Gradually add sugar; beat to stiff, glossy peaks.
Beat in vanilla and salt briefly.

Notes
These cookies are nearly foolproof as long as you don’t open the oven during the overnight rest. For variety, try swapping the chocolate chips with peppermint chips or leaving out the nuts for a nut-free version.
