In a mixing bowl, whisk together the Greek yogurt and honey until smooth and slightly glossy.
Line a baking sheet with parchment paper and pour the yogurt mixture onto it, spreading evenly with a spatula to about 1/4 inch thickness.
Sprinkle the fresh berries, chopped nuts, chocolate chips, coconut flakes, and a pinch of sea salt evenly over the yogurt layer, pressing them gently into the surface with your fingertips.
Place the tray in the freezer and freeze for at least 4 hours, or until the yogurt is completely firm and solid.
Once frozen, remove the sheet from the freezer and break the yogurt bark into uneven shards using your hands or a sharp knife, listening for the satisfying crack.
Serve immediately for the crispiest texture, or store in an airtight container in the freezer for up to 2 weeks, letting it sit at room temperature for a few minutes before breaking into shards again.
