Spread pretzels and nuts on a sheet of parchment paper. Rough chop chocolate and place in a microwave safe bowl. Microwave the chocolate on high for 1 minute, remove and stir until chocolate is thick and creamy. If the chocolate is not fully melted return the chocolate to the microwave for a few additional seconds taking care not to overheat the chocolate. Drizzle the melted chocolate over the pretzel and nut mixture and toss together with a mixing spoon, portioning into pretzel/nut clusters. Let chocolate set before serving.
Helpful Hint: Try flavored pretzels for an added surprise!
