1Place the wafers into a microwavable bowl. Microwave for a minute, stir and microwave for another minute. Stir again and if the wafers are not completely melted, microwave again for 30 seconds. Don't overheat, or the chocolate will seize up and be unusable.
2Stir in the broken pretzel pieces until all the pieces are completely covered with the chocolate.
3Spread the mixture on an aluminum foil covered cookie sheet. Chill about 1/2 hour or until firm.
4Break up the bark into smaller pieces. Store in an airtight container in a cool place.
