Line a baking sheet with parchment paper. This will prevent the chocolate bark from sticking.
In a microwave-safe bowl, melt the dark chocolate chips. Heat in 30-second intervals, stirring in between, until smooth and completely melted.
Pour the melted dark chocolate onto the prepared baking sheet. Spread it out evenly using a spatula to form a rectangle about 1/4 inch thick.
While the dark chocolate is still wet, sprinkle the freeze-dried strawberries and chopped pecans evenly over the top. Gently press them down into the chocolate to ensure they adhere.
In another microwave-safe bowl, melt the white chocolate chips using the same 30-second interval method until smooth.
Drizzle the melted white chocolate over the dark chocolate layer in a zigzag pattern for a decorative touch.
Finish with a light sprinkle of sea salt over the entire bark for added flavor.
Place the baking sheet in the refrigerator for about 30 minutes or until the chocolate is completely firm.
Once set, break the bark into pieces using your hands; it should easily snap apart.
Notes
Serve the chocolate bark on a decorative plate or in a gift box, perfect for gifting or entertaining.
