In a food processor, combine almond flour, dates, melted coconut oil, and sea salt. Pulse until the mixture is crumbly and starts to hold together.
Press the mixture firmly into the bottom and up the sides of a 9-inch pie dish. Set aside.
In a mixing bowl, mash 1 cup of blueberries with a fork.
In another bowl, whisk together coconut milk, honey (or maple syrup), chia seeds, vanilla extract, and lemon juice until well combined.
Add the mashed blueberries to the filling mixture and stir well.
Let the mixture sit for about 5 minutes to allow the chia seeds to absorb some liquid and thicken.
Pour the filling into the prepared crust, smoothing the top with a rubber spatula. Top with the remaining fresh blueberries.
Refrigerate the pie for at least 4 hours or until set. For best results, let it chill overnight.
Slice into 8 pieces and serve chilled. Enjoy your healthy dessert!
