Line an 8 by 8 baking sheet with parchment paper.
Melt the chocolate in a clean and dry heatproof bowl placed over a saucepan of barely simmering water.
Alternatively, you can melt the chocolate in the microwave. Do stir frequently so the chocolate will melt evenly.
Once the chocolate has melted, give it a stir so that it cools down a bit.
Pour the chocolate in the prepared baking sheet.
Top with the dried fruits and nuts. Sprinkle with some salt, if using.
Keep this in the fridge and let it set for about 10-15 minutes.
Cut or break the chocolate bark into smaller pieces.
Store in an airtight container at room temperature or in the refrigerator for up to two weeks.
