Preheat the oven to 160 deg C and line 2 small tart baking trays with coconut oil.
Chop and core apples and pears.
In a pan, heat up 100ml water and simmer the chopped apples and pears on a low heat for 15 minutes.
While the apples and pears are simmering, slice the cherries in half and remove the pips.
Take half of the cooked apple and pear mix and blend in a food processor with the prunes (stones removed).
Add the blended apple, pear and prune mix back into the pan, add the cinnamon and stir well.
Add the halved cherries to the apples and pears in the pan and simmer for 5 more minutes.
While the fruit is simmering, start to prepare the base. Firstly, melt the coconut oil in a pan on a low heat for a few minutes until liquid.
Grind the chia seeds in a coffee / spice grinder (chia seeds can also be bought ready ground).
In a large bowl, mix the ground chia seeds, oats, buckwheat.
Add the water and coconut oil to the dry ingredients in the large bowl and stir well until thoroughly mixed to form a dough like consistency.
Separate the mix out into 2 parts roll flat with a rolling pin, and place into 2 small trays, approx 12cm diameter, 4cm deep.
Bake in the oven at 160 deg C for 30 minutes.
