Step 1 Preheat oven to 180°C. Beat egg whites and salt until foamy.

Step 2 Gradually add sugar and continue beating until they hold stiff peaks and make a glossy, stiff meringue. Add vanilla, almonds and chocolate chips.

Step 3 Cover baking tray with baking paper. Drop teaspoonfuls of the mixture on the paper. Put in the oven, then turn oven off. Leave overnight in oven (or for at least 3 hours, until oven is cold) with the door closed.
