01 - Line a baking sheet (approximately 9x13-inch) with parchment paper to prevent sticking.
02 - In a medium bowl, whisk together the Greek yogurt, honey (or maple syrup), and vanilla extract until the mixture is smooth and fully combined.
03 - Pour the yogurt mixture onto the prepared baking sheet and use a spatula to spread it evenly, creating a layer about 1/2-inch thick.
04 - Evenly scatter the sliced strawberries and the roughly chopped mixed nuts over the surface of the yogurt layer.
05 - Place the chocolate chips and coconut oil in a microwave-safe bowl (or use a double boiler) and gently melt until smooth and liquid.
06 - Drizzle the melted chocolate over the yogurt layer, covering the strawberries and nuts.
07 - Transfer the baking sheet to the freezer and let it set for at least 2 hours, or until the bark is completely firm.
08 - Once set, remove the bark from the freezer and break or slice it into pieces. Store in an airtight container in the freezer until ready to serve.
