Cover a large flat surface with waxed paper.

In a large bowl, combine the popped popcorn, corn cereal puffs, corn chips, slivered almonds, and pretzel sticks.

Place confectioners' coating in a microwave-safe glass bowl.

Microwave for 1 minute.

Stir the coating.

Continue microwaving in 30-second intervals, stirring between each, until the coating is smooth and melted.

Pour the melted coating over the popcorn mixture, using a large metal spoon to distribute it evenly.

Mix thoroughly to ensure all ingredients are coated.

Spread the coated mixture onto the prepared waxed paper in a thin layer.

Let stand for approximately 30 minutes, or until the coating is completely dry.

Transfer the hardened mixture to a bowl for serving.

Store leftovers in an airtight container.
