Place almonds, walnuts, pistachios, coconut, cranberries and chia seeds in a bowl and toss. Pour 1/2 cup worth of caramel into the bowl with the nuts and toss with a spatula. Pour the nut caramel mixture into the lined dish and spread out until even throughout.
Place in the freezer for 3+ hours. Remove from freezer and cut into bars or squares.
Melt chocolate then dip each bar in the chocolate, using a spoon to press chocolate up on the sides of each bar. Place back on parchment paper and into the fridge for 10+ minutes.
Serve immediately and store in the freezer. (these bars fall apart easily so don’t leave them out too long)
