These look amazing!!! If you want to make something that's simple and quick yet delicious, you can just slowly melt some very high-quality dark chocolate 60% cocoa or higher in the microwave very slowly and stirring every 20 seconds so it doesn't break up. Then simply pour it on some parchment paper, and add some dried fruit or nuts. Then put it in the freezer for 5 minutes and there you have it some dark chocolate fruit/nut bark. If you're vegan, make sure the chocolate doesn't contain any milk/dairy.
