Slowly melt the chocolate chips in the microwave at 20 second intervals stirring each time between until smooth.
Drizzle the chocolate over the popcorn, and sprinkle a bit of nuts and m&ms, stir, and repeat until you have mixed all the ingredients in. Place in the refrigerator for about 10 minutes. Enjoy!
