In a medium size bowl, combine cream cheese, FAGE Total yoghurt, condensed milk, and beat with a handheld electric mixer until smooth. Add lime zest and juice and beat until well incorporated. Place the mixture into the fridge to firm up for up to 1 hour.
In another bowl, combine digestives and butter and set aside.
After the yoghurt has firmed up, alternate yogurt mixture and biscuits into a parfait glass and serve.
