Line a baking sheet with parchment paper to prevent sticking.
In a microwave-safe bowl, combine the dark chocolate chips and 1/2 tablespoon of coconut oil. Heat in the microwave in 30-second intervals, stirring in between, until fully melted and smooth.
Pour the melted dark chocolate onto the parchment-lined baking sheet, spreading it into an even layer with a spatula.
In another bowl, melt the white chocolate chips with the remaining coconut oil in the same way as the dark chocolate.
Once melted, drizzle the white chocolate over the dark chocolate layer in a zig-zag pattern. Use a toothpick or spatula to swirl the two chocolates together for a marbled effect.
Sprinkle the freeze-dried strawberries evenly over the top, pressing them gently into the chocolate to adhere.
Optionally, sprinkle a pinch of sea salt over the bark for added flavor.
Decorate with sliced fresh strawberries on top for a beautiful presentation.
Place the baking sheet in the refrigerator for about 1 hour, or until the chocolate is completely set.
Once solid, break the bark into pieces and serve.
Notes
For best results, ensure the chocolate is fully melted and smooth before pouring.
