Pre-heat oven to 180°C or 350°F and grease + line a small pie dish.
Add all crust ingredients to mixer bowl and process for 5 sec/speed 6/MC on.
Take the crust dough and press 3/4 of the mixture in to the prepared dish. Put it in the oven for 10 mins.
Take the remaining crust dough and place it on glad wrap. Press it out in to a square and pop it in the freezer - this will be used to top off the cherry pie.
In the mean time, without washing the bowl, put the filling ingredients in and cook for 10 min/100°C or 212°F/speed 1/MC off or until desired consistency is reached.
Put the prepared filling mixture on to the base. Take the crust dough from the freezer and cut in to 6 strips. Lay the strips over the pie and bake for a further 10 mins or until golden brown.
Notes
LCHF ADAPTATION: Swap the cherries for frozen strawberries or berries. Use 1/2 tsp xanthan instead of tapioca.
