In a food processor, blend almonds and shredded coconut until finely ground.
Add dates and coconut oil and pulse until the mixture sticks together.
Press the crust into a 9-inch tart pan and place in the freezer.
In a bowl, whisk together coconut milk, maple syrup, lemon juice, vanilla extract, and chia seeds.
Let the mixture sit for 10 minutes to thicken slightly.
Pour the filling into the chilled crust and refrigerate for at least 4 hours or until set.
Top with fresh berries just before serving.
