Prepare the yogurt mixture:
Line a large rimmed baking sheet with parchment paper.
In a medium bowl, stir together the Greek yogurt, maple syrup (or honey), and vanilla extract until smooth and fully combined.
Spread the yogurt:
Spread the yogurt mixture evenly onto the prepared baking sheet into a 10-by-15-inch rectangle.
Top with strawberries and chocolate chips:
Scatter the sliced strawberries on top of the yogurt and sprinkle mini chocolate chips evenly over the surface.
Freeze the bark:
Place the baking sheet in the freezer and let it freeze until very firm, at least 3 hours.
Serve and enjoy:
Once the bark is frozen, break or cut it into 32 pieces and enjoy! Serve immediately, or store in an airtight container in the freezer for a refreshing treat any time.
