Made with real mint to colour and flavour the filling, this slice is vegan and free of gluten and dairy. The chewy base is made of buttery pecans and Medjool dates, while the filling contains avocado to make it creamy, and shredded coconut adds texture. It is a treat you can store in your freezer and nibble on whenever you feel like something sweet. Soak the cashews a few hours before you start.
