In a microwave-safe bowl, melt the green chocolate wafers in the microwave at 15 second intervals, stirring in between, until the chocolate is completely smooth.
Dip the pretzels into the chocolate, letting any excess chocolate dip off, and place on a parchment-lined baking sheet.
Press a red candy heart into the chocolate so that it really sticks.
Place the chocolate pretzels in the fridge and allow the chocolate to harden completely before serving.
