To make Meringues, first cover a baking sheet with parchment paper. Draw two three inch circles on the paper using a dark colored pencil. Turn the paper over, and secure with freezer tape.
Combine room temperature egg whites, cream of tartar, and salt in a mixing bowl, and beat at high speed until soft peaks form. Gradually add a quarter cup of sifted powdered sugar, 1 tablespoon at a time, beating until stiff peaks form. Do not underbeat. Fold in chocolate chips and vanilla.
Divide the egg white mixture evenly between the 2 drawn circles. Shape the meringues into nests using the back of a spoon.
Bake in a preheated oven at 250° for one to one and a half hours or until dry. Turn the oven off, and cool the meringue nests in a closed oven for at least 3 hours.
Carefully remove the meringue nests from paper. Top each with a mixture of sliced strawberries and sugar.
