1. Combine the Greek and natural yoghurts together and stir in the Sweet’N Low and vanilla extract until thoroughly mixed.
2. Using a third of yoghurt mixture, place a layer into the base of each glass, followed by a layer of blueberries. Repeat with another layer of yoghurt followed by strawberries.
3. Top the glasses with a final layer of yoghurt and top with a sprinkling of nuts.
4. Chill until required. If chilling overnight add the nuts when about to serve.
As alternative try including different seasonal fruits, like blackberries or peaches.
Note: if preferred use low fat yoghurts to reduce the fat content.
