Remove white chocolate chips from jar. Empty remaining jar contents into a large mixing bowl, and mix thoroughly.
Place white chocolate chips into a microwave-safe bowl. Melt white chocolate chips in the microwave for 30 seconds. Remove and stir until melted. If additional time is needed, check at 15 second intervals. (You may add 1 teaspoon solid shortening to thin chocolate mixture, if necessary.)
Pour melted white chocolate chips over snack mixture. Stir until snack mixture is evenly coated. Spread mixture in a single layer over waxed paper, and allow to cool completely.
Break mix into smaller pieces, and store in zipper food storage bags or an air-tight storage container.
