Preheat the oven to 160C(320F) fan-forced and line a baking tray with baking paper.

Mix the almond meal, sugar, egg whites and vanilla together until everything is well combined.

Roll a heaped teaspoon of mixture at a time into a ball and place it on the tray. Leave a little space between each one but don't worry too much as they don't spread. Flatten each one a little.

Bake the cookies for 15 to 20 minutes or until browned on top. Leave them to sit on the trays for about 5 minutes then transfer to a wire race to cool completely.
