Fill a small saucepan with water and place a medium size glass bowl on top of it. The bowl’s bottom should not touch the water in the pan. Over medium low heat bring water to a simmer.
Add chocolate and butter to the bowl and stir until it melts.
In another bowl mix together the sugar, eggs and vanilla extract.
Slowly add the egg mixture to the melted chocolate, stirring constantly, until the sugar has dissolved.
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 the mixture sit for about 10 minutes so it can cool enough that it can be formed into a shape.
Cut two large pieces of parchment paper, or wax paper, and divide the mixture between the two pieces. Tightly roll the chocolate mixture into a tube (diameter should be about 2.5 inches). Twist the ends of the paper and tie each end with a string.Refrigerate for at least 2 hours or overnight.
When you are ready to serve it unwrap the Chocolate Salami, sprinkle a little powdered sugar on the counter, and roll it in the powdered sugar, lightly dusting the outside. Slice and serve.
