Divide 1/3 of the meringues into the base of 4 small glasses.
Layer with 1/3 of the yoghurt and 1/3 of the fresh (or defrosted) berries.
Add 1/3 chopped white chocolate (if using).
Repeat with another two layers using the remaining meringues, yoghurt, berries and chocolate (*chocolate is optional).
Sprinkle a tiny amount of meringue over the top and serve.
