In a bowl, mix graham cracker crumbs with melted coconut oil until well combined.
Press the mixture into the bottom of a pie dish to form the crust. Chill in the fridge for 15–20 minutes.
In a saucepan over medium heat, combine blueberries, maple syrup, and lemon juice. Cook until berries break down and the mixture thickens slightly, about 5–7 minutes.
Stir in chia seeds and remove from heat. Let the mixture cool.
Spread Greek yogurt evenly over the chilled crust.
Top with the cooled blueberry chia mixture.
Drizzle with honey if desired and chill the pie for at least 2 hours before serving.
