Vegan key lime pie

Whizz all the crust ingredients in a food processor with an S-blade. Transfer the mixture to a 23cm loose-based tart tin. Using your fist, press the mixture evenly into the base and sides of the tin.

To prepare the filling, blend all the ingredients in a high-speed blender on a high-speed setting, or pulse in a basic blender until smooth and creamy.

Pour the filling onto the crust and shake the tin a little to even it out. Chill for a minimum of 3 hrs to set. Decorate with the lime zest and slices, if you like. Will keep in the freezer for up to 2 months. Defrosted in the fridge, it will keep for 1 week.
