01 - Line a 9x13 inch baking sheet with parchment paper, ensuring complete coverage to prevent sticking.
02 - In a medium mixing bowl, combine Greek yogurt, honey or maple syrup, and vanilla extract. Whisk until completely smooth and well incorporated.
03 - Pour the yogurt mixture onto the prepared baking sheet and spread evenly with a spatula to approximately 1/2-inch thickness.
04 - Distribute sliced strawberries evenly across the yogurt surface. Sprinkle with mini chocolate chips and chopped pistachios, pressing gently to adhere.
05 - Place dark chocolate chips and coconut oil in a microwave-safe bowl. Microwave in 20-second intervals, stirring between each, until completely smooth and melted.
06 - Using a spoon or piping bag, drizzle the melted chocolate mixture back and forth over the yogurt and toppings in an attractive pattern.
07 - Transfer the baking sheet to the freezer and chill for at least 2 hours, or until completely firm throughout.
08 - Remove from freezer and break the bark into irregular pieces. Serve immediately while frozen. Store leftovers in an airtight container in the freezer for up to 2 weeks.
