Melt chocolate. Fill a small saucepan with water and place a medium size glass bowl on top of it. Bring water to a simmer. Add chocolate and butter to the bowl and stir until it melts.
Add biscuits. Continue to stir until the chocolate mixture is completely smooth then remove it from the heat and fold in the broken Maria cookie pieces.
Let cool. Cut two large pieces of parchment paper. Divide mixture in half. Tightly roll the chocolate mixture into a tube. Twist the ends of the paper and tie each end with a string. Refrigerate for at least 2 hours or overnight.
CAN YOU MAKE CHOCOLATE SALAMI AHEAD OF TIME? Yes! This is an awesome dessert to make for parties and the holidays because it can be made ahead of time and stored in the refrigerator for up to 1 week, or stored in the freezer for up to 1 month. If you are storing it in the freezer I recommend placing the wrapped Chocolate Salami and placing it in a freezer bag to keep it fresh. Also remove from the freezer and place in the refrigerator 2 days before so it will be thawed by party time.
